Are you referring to the Pilot Sport 3 (PS3) or Pilot Super Sport (PSS)?

In some area, PS3 is kind of not true replacement for the PS2 and tuned more towards the comfort.
PSS is regarded as the direct replacement of PS2 and not the PS3.

It will be great if Michelin is going to release PSS (assuming you were referring to them and not the PS3) with extra size configurations as currently, there is very little choice on the 17s and nothing for the 16s or 15s.

Hi Kaz

This is the reply I got from the Michelin Customer Engineering Manager

"How desperate is the car for tyres?

If you can wait until August/September this year, we are launching the two sizes below in Pilot Sport Cup2 which would be perfect for the car.

So, if it was mine, and I could wait, I would. If it's urgent you could mix the PS2 & PS3, but they aren't the ideal combination"

ContiSport 3s are still good "all round"* performance tyres - I've got them on my FD2 CTR, but I suspect the PS Cups will be better for the NSX...

Hi,

I'm a newbie and have just bought a '91 NSX that needs new tyres. I can find 205/50R15 and 225/50R16 in 'W' speed rating but not 'Z'. Can anyone recommend a supplier that could help please? I've tried all the usual suspects - as well as the manufacturers - but can't find anything!

Thanks.

Welcome to the fourm and the owners club. I suspect you will be lucky to find the speed rating as fitted to the original NSX. I also have a '91 and use yokohama advan neova V rating on the front - I was more concerned about the compliance of the tyre and the handling character. Although you cant get the higher speed rating as long as you inform the insurance company you should be ok to run them on the road.

Please note that even with the same tyre size on the sidewall, the actual circumference is different depending on the tyre structure and manufacture so using different size from OEM one may trigger the TCS under certain conditions.
For example, you may find that going through the small roundabout is fine but when driving at moderate speed through mid – large roundabout, you may activate the TCS depending on the tyre F/R combination and the tyre manufacture/structure.
Personally, I don't like the TCS on non-DBW model so I will disable it.

By the way, there are lots of misunderstanding on the speed rating.
Whether the insurance company knows it or not is a different story.

First, the ZR is a speed category and not the max speed.
It’s also from the ancient standard so not much used these days since the introduction of the new standard.

While many people thinks that the speed rating is showing the max speed limit, it’s not that simple.
It is the max speed under defined conditions (defined increments of speed/time under defined load, etc) and one of the key condition is having the tyre loaded at its max Load Index weight while testing it.

So, even if your tyre has speed rating of W (270kph, about 169mph), it doesn’t mean it’s not safe to use on our NSX as the Load Index will be around 86 (530Kg) and this is per tyre.
Again, the insurance company may ignore this fact……

If you have a chance to visit the tyre manufacture’s tyre dyno, you will understand how thoroughly and strictly your tyre was tested and also recognise the importance of the tyre maintenance.

Looks like Michelin have decided not to do any tire that fits 215/40/R17 and 255/40/R17 (Original 02+ tyre size). So after hours searching the internet it looks like you can get Bridgestone RE050's but I think in one of the sizes the tire is a run flat. Or Yokohama AD08r's.

I need to get this sorted before Euro trip in May.

I've been pestering our European tyre supplier for Michelin Pilot Sport Cup 2s or Toyo R888s for ages now but getting 215/40/17 and 255/40/17 together in particular brands / models is impossible! I'll most likely be going for AD08Rs as I don't really want different tyres on different axles.

17-04-2016, 07:26 PM
After only 3,500 miles my Toyo 888R rear tyres are now worn out 😳
So I thought I would try the TR-1's on the basis of what nobby thinks of them so far, they certainly look good and at just £125 for the pair 👍 I can't really go wrong, hopefully good for 10,000 miles at least now.

First impressions this afternoon are very good and with the super sticky 888R's on the front for good sharp turn ins I'm hoping this will be a great combination.

I've no idea how you have your chassis set up but to chew a set of rears so quick youre either hard on tyres by way of driving style or they were (IMHO) way too soft for road use.

I had F1's do 18k on the rears, Kumho's that did similar ad offered stiffer sidewalls, and current AD08's have covered 10k with plenty left to go ...

Agreed. I've done 11k on the current set of RE050A rears, which are still on 3-4mm. Just wondering whether I can get away with doing another 1,500 on the NSXCE trip or whether to change before I go.

I've also had a couple of sets of F1's over the years (shame their not available now) and the tread pattern on the TR-1's are very similar so that's a positive. In fact I had to replace the fronts due to age as they never seemed to wear down, where as the 888's on the front are wearing out rapido, probably another 6k max which isn't a lot for fronts.

To be honest the 888's were the soft compound version but all the same I didn't expect such a poor mileage from them.
They did inspire extreme confidence though on dry twisty roads but the first hint of moisture I did tend to back off equally as much.

I did like the AD08's when I had 17"'s fitted, it's just a shame they're not made in smaller sizes.

I'm looking forward to seeing how they feel on the Spa trip and round the track, I just hope it will be dry.

Not sure of your driving environment/style or how you are setting up the car and any changes made while using the R888 but if you managed to get 3,500miles out of R888 on NSX, you haven’t driven it hard enough. ;)
Probably not many track days and mainly street driving.

Depending on the driving environment and session used, non-OEM size A048 on spare wheel set on another NSX only lasted less than 1,000miles so more than 3,000miles on competition compound, it's either a bargain or not suited for the main purpose.

Not sure what wheels you are using but AD08 used to be available in all OEM tyre sizes.

I've ran Hankooks for many years and been very happy with them. But the Yokohama AD08R is itching me. One thing I worry about is tyre wear. I get 6-7k miles out of the fronts and about 4k miles out of the rears (CTSC and spirited street driving). As some of you have switched to AD08R how do you compare them to a V12 or S1 or F1-GSD3 regarding tyre wear? Yokos are expensive and I'm not willing to change them twice a season.

Kaz-kzukNA1
07-05-2016, 01:32 PM
Hi, goldnsx.

I have driven V12 on a few NSX but not on my NSX so can't comment on the tyre wear for it but I went through several sets of GSD3s.
I'm not hard on acceleration but fairly hard on braking.
It's my everyday car and thus, drive in dry/wet condition, mainly moderate to high average speed with very little city traffic, mainly A/B road and some motorway journey.
With my driving style and environment, I used to cover 9K – 11K miles out of GSD3s.

I went through a few sets of AD08 (not R) and about to switch to AD08R.
With AD08, I am covering about 10K miles before replacing under similar driving style/environment so although it all depends on many factors, if you have the data from your GSD3 usage, AD08 seemed to be similar or little bit faster to wear out.

Obviously, even with the same driving style, the tyre pressure, tyre/road/track surface temperature and wet/dry condition, etc will have huge impact on one's tyre wear and with dramatically changing weather conditions over the recent years, it won't be easy to predict the wear but hope you can get some idea from this.

Hi Kaz

Thanks for your input. My experience with GSD3 dates back a little bit but they covered around 1k miles more out of a set than the Hankooks and this even with in slightly smaller tyre sizes (205/245). So I guess that Hankooks and AD08R should be comparable in wear. So I definitly give them a try. One AD08R is nearly double the price of a Hankook in 215/40/17 and it's not available in 225/35/17 but a stickier 215 will more than compensate I hope.

Yes, you're right, actually I was stepping up and I'm running 215/255 or 225/255 on 17/17 resp. 17/18 now. 205/245 was with OEM 16/17 (sold) where it was hard to find matching tires (Hankook and Goodyear were the only reasonable option back then).
I prefer the 225/35/17 over the 215/40/17 because it offers more rubber and is slightly smaller in diameter, smaller enough to avoid rubbing on the inner wheel well on a lowered car fully turned in. But the choice in 225/35/17 is very limited. Hankook does offer its V12 which is working very well. But you can't mount this size on an 17'' OEM front rim as the minimal required width is 7,5'' while OEM 02+ is only 7'' (shame on Honda).

Spoke with Yokohama HPT yesterday as Neova AD08R in 245/40/17 was out of stock in May.
It's now back in stock so if you need this specific size, time for the shopping.
I reserved mine yesterday and going to install it within a few days.
255 is/was always in stock so that can be a good compromise if you miss this time although Neova seems to be bit wider under load than other models.

Anyone besided me gave the Federal 595RS-R a try? It is available in oem 2002+ spec: 215/40 and 255/40/17 inch. I compared the RE050A and the Federal at the track at same day and same conditions. The brake point and curve speed is beyond better than the RE050A. This Federal is also realy cheap, talking about 500 Euro the set of four! And by the way: the Federal has also way more grip the first 100meter than the RE050A does. I love the RE050, but performance-wise the 595R beats him. BEST band for the money IMO.

Good call Austrian type-R, I considered those a few months ago as they looked good and certainly great vfm.

The AR-1's look fantastic and as I now do mainly low mileage each year now I will probably try a set of these when my 888R fronts wear out, which won't be long.

Are they street legal or only for track use as the tread pattern is even more extreme than my 888R's ???

I'm back with the Goodyears again. The Eagle F1 Asymmetric 2 or 3 comes in NSX sizes or in 17/18. The tires are simply great and it's superior to the Hankooks I had before. The breaking power is far better. The better longlivity compensates for their higher price but it adds better quality over its livetime. I had Goodyears before but had to switch to another brand as the F1 GS-D3 was not easy to get anymore and there was no sporty substitute in NSX sizes.

The last Hankook Evo2 was a bit of a disappointment with only 7'000 km in 255/40/17, the missing rim protector too.

These are what I'm going for with my re-build and wheel upgrade. I have them on my S2000 after the guys at Centre Gravity recommended them and they are an excellent all round tyre. I've taken my S to Curborough Sprint Circuit a couple of times and the tyres performed excellently. Glad someone else is singing their praises.

You won't regret it. :) The S2000 is even more critical in terms of fitted tyre. Good to know they work there also.

In the early years I had Bridgestones, S-01, S-03 and the last one I had was the RE050A. It's a stiff and heavy tyre with excellent performance. They also set the record in longlivity (I wonder how I've reached that), contrary to my expectations. But they are beast to mount on the rim. I prefer a medium-soft sidewall now. It doesn't make sense to have one of the lightest rims on the car and fitting an extra heavy tyre like a Bridgestone if there are equivalent and lighter substitutes. That's why I won't go back to Bridgestone again.

Hi. My rears are now old and need replacing. They are Yokohama 245 40 ZR 17 95Y.

I've read Kaz mention Yokohama Advan Neova AD08R and looking online I can find these in 245/40 R17 W(91).

Are these the closest match now available ? I've no idea myself. I drive it slowly, no track days, etc. so don't need long life or high performance just the one that won't cause insurance or traction control issues as Kav has also mentioned.

Is something wrong with the speed rating of these new Yokohama ones or can you get others which are correct but cost the earth ?

Also, does anyone recommend a specific fitter in the north west as I'd like the alignment checked too.

Thanks

goldnsx

The Yokohama Advan Neova AD08R is a very sporty tyre, nearly a semi-slick with a soft tyre compound. Ususal drawbacks with semis: loud, expensive, high wear and not that very safe in rain or at low temps.

If you drive conservatively I'd recommend a good known brand of sport tyres, not semi-slicks to avoid the potential issues mentioned above. Goodyear, Bridgestone, Hankook (in this order) are my favorites for cruising up to spirited street driving.

Yokohama has been 'famous' in the past for NOT having a set of the same tyre model for the front AND the rear of the NSX.

W (up to 270 km/h) would be no problem in Switzerland as it would be in Germany.

Alignement: I know more places NOT to go to then professionals.

I wrote the same thing here regarding the speed rating but whether the insurance company is aware of this fact, that's another story.
Just ask your insurance company and also ask them what happens if the owner installs winter tyre for snow driving.
This was raised to the insurance committee several years ago when we had lots of snow in one winter here in UK.

Speed rating is not as simple as just showing the capable max speed.

There is a reason why it's written together with the load index.
If you have ever visited the tyre manufacture's dyno, you will understand how the speed rating is tested.
The tyre is loaded at the level of load index weight and then the speed is increased at specified rate/time to achieve the max speed.

Speed rating is based on flat surface and load index of 91 and 95 are both over 600kg.
So, if you are driving on the flat road surface at high speed and if your loadcell is reading more than 600kg at each rear corners, you better check your chassis or open the boot to see what's in there.

On flatpatch with corner gauge, standard NSX will show about 350 - 450kg at each rear corner depending on the spec/side and you won't be able to generate enough downforce to achieve load index figure at each corners on flat surface even with the NSX-R aero package.
So, even with W rating of 270kph and unless you can magically generate well over 600kg corner weight at each rear tyres, you are fine. Again, if you are worried about the insurance, just ask them.

Based on your other posts, your NSX is likely to be NA1.
If you have ever tested the NA1 NSX out of the factory without any modifications on the proving ground, you will find it quite challenging to exceed 270kph without following wind.
The speedo on the dash is not accurate enough at this speed region so you need different equipment for this.

NSX is very sensitive to alignment change.
I used to spend more than 2Hrs for adjusting with the place I use.
As goldnsx suggested above, it's not the equipment but more of how the operator adjusts it.
Hope another owner in your area can recommend you a place.


Regarding the tyre, that tiny contact patch is what you are relying to turn/stop the well over 1,000kg metal mass energy under all sorts of conditions.
5mph is enough to throw your body forward if you hit solid wall.
Regardless of NSX or not, please select decent one.
For me, tyre is another engine on our NSX.

Like Kaz, I'm very impressed with the AD08Rs on the NSX. Once they've warmed up a bit, but that's also true of the specific-Yokos on the Leg End.

I had the F1As on the Prelude and that was a fantastic car in all conditions. If you do not drive the NSX like you stole it, I cannot see why they'd not be suitable.

I had the F1As on the Prelude and that was a fantastic car in all conditions. If you do not drive the NSX like you stole it, I cannot see why they'd not be suitable.

HTH.

I too am very impresssed with the Yoko Advans which I bought on Kaz's recommendation. Excellent tyres and not "loud" at all nor any problem in the wet - in fact remarkably stable so I am not sure why that comment was made unless it refers to track speeds. They are not cheap but a bit of Googling can usually turn up a pair at a good price and yes, they are not the longest wearing although given my limited annual mileage that is not a problem for me.

As long as semis are in newer condition they are not loud. Semis usually get loud when they are worn below 50%. The risk of aquaplaning also dramatically rises with wear. In the UK you have quite a lot of rain...

The risk of aquaplaning also dramatically rises with wear. In the UK you have quite a lot of rain...

This to me is the key point with the AD08R (I've got them fitted and I rate them highly, for reference) - it's a good tyre as long as you understand its' design compromises. Specifically aquaplaning - it's got very limited tolerance for standing water, like all 'track day tyres'. I'd also treat it with a little respect in low temperatures, but that's about it...

So if your NSX is a fair-weather friend (so to speak), then aside from extra cost vs the RE040/050A pairing (which I had before and are more 'all-round'), the AD08R is an upgrade - it's more precise, it gives more feedback, it's not noisier (so far), and it's got a fair bit more dry-weather grip. Looks good too, if perhaps being ever-so-slightly TOO wide and square-shouldered.

If you've an NA2 with 17"s all-round, there are more options - I THINK you can still get Michelin Super Sports in those sizes, and that's an excellent tyre - broadly similar performance characteristics to the AD08R but better wet-weather behaviour.

08-05-2017, 08:23 PM
My NSX is a little bit spoiled and/or I'm a little bit too 'sissy' to drive in wet conditions, I only drive it in dry conditions. I also understand the importance of 'grippy' tyres at the front esp. while braking. Maybe the AD08R would have been a good choice but the Goodyears are the better compromise for me I think. It's a little step-up over Hankooks. But the bigger step-up was the complete brake system of the 99/00 model in my case. As I've just bought Goodyears for my two sets I'll have to wait another two years until I can give the AD08R a try. Good to know the rubber of my tyres doesn't get old. Old compound is the worst thing to have.

I use Toyo's 888R on the front, now they are what you call "semi slick" but I find as long as you adapt your driving style to the road and weather conditions you shouldn't run into any problems and as for ageing, 5-6,000 miles max but the grip is phenomenal on dry roads.

Suggestions for 15-inch fronts? The supplies seem to be getting scarcer, and a lot of the suggestions early in this thread are no longer available. I had looked for the Goodyears (to match the rears), but they seem to be long gone.

The easily available options (via the type retailers' online databases) seem to be Pzero, AD08R (bit concerned by the wet weather worries!) and Toyo Proxies.

Thoughts?

Unless you use your car as an everyday driver the 888R's are amazing and for less than £100 each also great VFM.

I only use them on the fronts and with the large side walls they also offer terrific compliance and a lot of sensitivity.

Even in torrential rain I find you can still drive with confidence at normal speeds for the conditions and when the roads become dry the front end grip you get from the huge contact patch of soft rubber makes you realise why these tyres are used in competition racing, seriously amazing performance.

I must admit that it can be difficult to find a recognised supplier but eBay there's no problem.

You won't regret it. :) The S2000 is even more critical in terms of fitted tyre. Good to know they work there also.

In the early years I had Bridgestones, S-01, S-03 and the last one I had was the RE050A. It's a stiff and heavy tyre with excellent performance. They also set the record in longlivity (I wonder how I've reached that), contrary to my expectations. But they are beast to mount on the rim. I prefer a medium-soft sidewall now. It doesn't make sense to have one of the lightest rims on the car and fitting an extra heavy tyre like a Bridgestone if there are equivalent and lighter substitutes. That's why I won't go back to Bridgestone again.

Looking to change my tyres (215/40/17s on the front and 255/35/18s on the rear) I'm looking at the Michelin Pilot Sport 4 and the Michelin Pilot Sport 4S. Anyone got these, and what do they think?

Good morning !, what do you think about the tires Yokohama Advan Sport V105 ? I am going to install the original NSX-02 wheels in my car, and I do not know if the flanks are strong enough, I do not find many opinions.

I usually use AD08R, I am very happy ,but they last me very little on the rear wheels. I have the full conversion NSX-02R , suspension, rear swaybar, front sway bar but of the first type R that is somewhat thinner than the 22 mm from 2002 and to drive is much better , Front reinforcement bar,and I have eliminated the lower front bar one and the car is much better(as recommended Kaz :) ), before it was too rigid in front, and 02R engine reinforcement bar,with all the aerodynamics and less weight.

I also use the alignment the last Type-S and I am happy , the setting NSX-02R It is very aggressive for me.


Well, just know if this tires Yoko Sport V105 is a good option, it's cheaper, but I do not know if it will be a good option for my car

Thanks

Not so many feedback of V105 on NSX even in Japan.
The owners in Japan tend to go for the OEM one (still available) or AD08R, RE71R, Direzza ZII/III, etc or slick tyres but at reasonable price.

The V105 is within the Yoko's top brand Advan family and the only tyre above it is the AD08R that was developed more towards the grip level whereas the V105 is focused to be selected as the OEM tyre supplier to fulfil the wide variety of strict demands of car manufactures.

Therefore, based on the above and feedback from owners of other makes/models, looked to be very good all-rounder.

I have never seen any replacement tyres with the same level of side shoulder stiffness as the OEM one in OEM size.
AD08R or RE71R are nowhere near the OEM stiffness.
Obviously, if you use different tyre size, that's a different story.


Your chassis setup plays big part on actual feedback/feeling so can't really tell just from the tyre point of view.
Addition to this, the driver is one of the biggest key factor on tyre performance/characteristic feedback.
It's upto the driver on whether one can use the full performance of the tyre or not and how well one can adjust one's driving style to it.

Being fortunate enough to be in the passenger seat of many FIA license holders including the F1 drivers and among them, one of them took me out around my area in his LHD NSX.

His NSX had very basic tyre (it was really cheap one) with almost worn to the limit.
The alignment was completely unbalanced.
It was his first visit to my place but still, his driving was so smooth and much faster than me especially with the braking.


So, in my view, anything with E marked tyre, you can use it and it's up to the driver.


Type-S alignment on European road….
Probably it's your rear toe and camber chewing your tyre then…

After a while I drove my NSX with JDM alignment in UK, I reduced the rear toe but with bit extra camber as I didn't like or even felt dangerous on wet UK road with uneven surface water.
Since then, went through so many tyre sets but even with AD08R, never felt uncomfortable even in wet condition.
Still, it's a compromise compared to the OEM tyre......

In the past, one disturbing thing with Yokohama was that they changed the models much too frequently. Even if you found a matching set for the front and the rear in one year you could be sure that you won't be able find them in 1-2 years. That's why I stayed away from Yoko. A mixed setup is a no-go IMHO. I hope it to be more continuous with the AD08R.

NSXR Spain
29-01-2018, 09:39 AM
Thanks Kaz for the info!! :)

I ordered two rear tires Yokohama Advan Sport V105 that I will ride on the original rims 2002, and I will tell you my impressions

I like driving with the car something hard suspension,I've spent a lot of time on circuits too and that's what I like, what happens is that I have to find a balance to roll on the roads of my city, with potholes, drop-offs, etc, and the typeR alignment is too aggressive from there, I put a thinner front bar and eliminated the lower front bar.

I made a Madrid-Nurburgring two years ago trip with my nsx and I ran out of back rear tires(with NSX-02R alignment), I ate them inside and I had to buy some there to go back to Spain. I bought some Nokian because there were no others, and I was surprised at how good they were.

In my city it does not rain much, and the time in Madrid is usually warm, besides I do not take the car when it rains.

the alignment of the type S does not go badly to me, when taking the car low and with the suspension of the Type R 2002, I believe that it is the most similar thing,anyway, I accept suggestions

Many thanks :)

Hi Kaz,

I think the AD08R might be the best choice for sidewall stiffness in the absence of the OEM tyre (Dunlop SP Sport 8070 according to my door sticker!?) according to EVO's unscientific squueze test.

Yet more advice please - I currently have Yokohama AD08R Z215/40W17YO (or 83W probably) on the front and need some rear tyres.

I am looking at the Yokahama Advan Sport V105S 255 40 R17 98Y (Black Circles fitted £137.56) or Yokahama Advan Neova AD08R 255 40 R17 94W (£176.11). As the speed rating on the Sport version is the required “Y”, I am tempted to go for those as a higher load rating is apparently okay vs the Neova which has the correct load rating but a lower speed rating at “W” (and a higher price!). I use the car as a daily on normal UK roads only.

Noting Kaz’s earlier comments on the V105, would that be okay?

Many thanks,
K

Kaz-kzukNA1
03-04-2018, 10:10 AM
I wrote the same thing here regarding the speed rating but whether the insurance company is aware of this fact, that's another story.
Just ask your insurance company and also ask them what happens if the owner installs winter tyre for snow driving.
This was raised to the insurance committee several years ago when we had lots of snow in one winter here in UK.

Speed rating is not as simple as just showing the capable max speed.

There is a reason why it's written together with the load index.
If you have ever visited the tyre manufacture's dyno, you will understand how the speed rating is tested.
The tyre is loaded at the level of load index weight and then the speed is increased at specified rate/time to achieve the max speed.

Speed rating is based on flat surface and load index of 91 and 95 are both over 600kg.
So, if you are driving on the flat road surface at high speed and if your loadcell is reading more than 600kg at each rear corners, you better check your chassis or open the boot to see what's in there.

On flatpatch with corner gauge, standard NSX will show about 350 - 450kg at each rear corner depending on the spec/side and you won't be able to generate enough downforce to achieve load index figure at each corners on flat surface even with the NSX-R aero package.
So, even with W rating of 270kph and unless you can magically generate well over 600kg corner weight at each rear tyres, you are fine. Again, if you are worried about the insurance, just ask them.

Based on your other posts, your NSX is likely to be NA1.
If you have ever tested the NA1 NSX out of the factory without any modifications on the proving ground, you will find it quite challenging to exceed 270kph without following wind.
The speedo on the dash is not accurate enough at this speed region so you need different equipment for this.

NSX is very sensitive to alignment change.
I used to spend more than 2Hrs for adjusting with the place I use.
As goldnsx suggested above, it's not the equipment but more of how the operator adjusts it.
Hope another owner in your area can recommend you a place.


Regarding the tyre, that tiny contact patch is what you are relying to turn/stop the well over 1,000kg metal mass energy under all sorts of conditions.
5mph is enough to throw your body forward if you hit solid wall.
Regardless of NSX or not, please select decent one.
For me, tyre is another engine on our NSX.


Kaz
I've touched on this several times so I'm just going to quote my old post.
If using the default display setting of this Forum, it's on Page 30, post #294 of this very thread.

Haven't seen the feedback on V105 from @NSXR Spain but not sure how many miles he managed to cover through the cold winter period.
Even snowed during the last Barcelona F1 test.
The feedback from other owners doesn't mean it will be the same for you.

Personally, in Europe, as long as you have E marking, you can use any tyres and it's up to the driver on how to drive but any of the tyres you mentioned (V105, AD08R) above would be fine for your driving conditions.

Any feedback from those who've had Pilot Sport 4 fitted to their NSX? I've got a spare set of 17/18 wheels I need to put some tyres on, and with the wider choice of options in that size was wondering if the PS4 makes for a better all-rounder than the AD08R.

Different cars so possibly doesn't help, but I've got PS4 on my FD2 and AD08R on the NSX.

The PS4, while not squidgy, don't have quite the same sidewall stiffness as the Yokos, but with a small-enough sidewall (40-profile on the FD2) they're perfectly good enough in that regard - certainly as precise as any mainstream tyre I've tried. They also don't need to 'warm up' like the Yokos do to give their best. And of course, they'll be a huge improvement in standing water...

If I was taking my NSX on track semi-regularly, I'd go with the AD08Rs for the breadth of ability and extra outright grip they give. Otherwise if I'd got the choice (I'm on OE 16/17, so I don't), I wouldn't hesitate to go for PS4...running the AD's I'm always conscious of the weather when planning to go out in the NSX...light rain isn't a problem, a downpour could be...

I've actually driven very spirited at high speeds in torrential rain on both A & M roads with my AD08's over the years and found the grip they give to be very confidence inspiring. 9/10 for performance levels in my opinion.👍

PS2 and PS4 are used on Porsche and gives fantastic grip.
AD08 on NSX is the same.

I think both are good tyres for Grip but may have different wear rate. They both maintain their grip even when worn unlike other tyres.

As the 17/18s would have quite a low aspect ratio, and I do not intend to track my car, it sounds like the PS4 will be a good choice for that set of wheels. :)

I have the OEM 16/17s on the car right now, and will one day need to replace the tyres on those (currently Potenzas) . . . but that's a slightly different question!

The Potenza/AD08R debate is reminiscent of the tyre choice for the Lotus Elise S2, which also has a front tyre size unique to that vehicle. The original OE tyre for the S2 was the Bridgestone RE040, with Lotus later moving over to the Yokohama AD07. These days people tend to run the unique size of AD07 on the front, with AD08Rs on the rear as they are available in the right size cheaper than the Lotus-specific AD07.

The general wisdom in the Lotus community seemed to be that the AD07/08/08R performs far better in the wet than you would expect for a tyre of that type, where the RE040 performs worse in the wet than you'd expect. I was never sure if the aggressive look of the Yokos led people's expectations to the conclusion that it would have zero wet grip and that for it to have any wet grip at all was seen as exceptional!

I'd be curious as to whether there's a consensus here as to which of the Potenzas or AD08R is better in adverse (read: British, rainy) conditions . . .

I'd be curious as to whether there's a consensus here as to which of the Potenzas or AD08R is better in adverse (read: British, rainy) conditions . . .

Two things at play here:-
1) Compound. The AD's have a compound that performs genuinely well on wet tarmac, which is where the 'Lotus wisdom' (sounds Buddhist! ;) ) comes from. Not so sure about very-cold weather, but that's a different kettle of haddock.
2) Tread pattern. The AD's have a very 'sparse' tread pattern, and as a result a much greater risk of aquaplaning (for equivalent tread depth) than a more 'normal-looking' tyre like an RE040.

...which is to say if there's standing water I'll be driving like your grandmother on AD's, but if it's just wet I'll probably be happier on them than on most Bridgestones (old S02's excepted - they were very good).

You could argue that to own a Lotus requires a somewhat Zen mindset . . . so yes, perhaps there's something in the Buddhist thing!

The compound vs tread pattern tradeoff makes sense. :)
Driving carefully in torrential rain is an acceptable compromise for AD08Rs through the temperate months, but it might get a bit tricky in full winter conditions.

I can certainly report that AD07 LTS does not respond well to the cold. There was a period when I had to commute through winter in my Elise - after one too many occurrences of ABS activation/alarming roundabout understeer at what I considered mild commuting speeds I switched to winter tyres. They noticeably dulled feedback and response, but for the ability to actually turn in on a roundabout or perform an emergency stop that wasn't a panicked, chirruping slither they were worth their weight in gold. And on the day it actually snowed and I got to proceed happily in a lane of fresh snow past a line of BMWs spinning their wheels in slush . . . bliss!

I rather suspect that for effective all-year use of the NSX I'd have to swap AD08Rs for Sottozeros or similar come November. The Potenzas have so far been tolerable in near-freezing conditions; PS4 or other less compromised tyres may also prove tolerable in such weather.

. . . have I just convinced myself I need to buy *three* new sets of tyres?

I have compared 3 NSX within very short period but please note that I only drove PS4 for just about 50miles, never in wet and not my NSX so never pushed hard enough.
Chassis setup including alignment difference plays big part but because it's not my NSX, not possible to achieve the same setup or push hard.
Please take these into consideration when reading the following feedback.

Car #1: facelifted, Coupe, OEM 17/17 wheel, PS4
Car #2: facelifted, Coupe, OEM 17/17 wheel, AD08
Car #3: popup, Coupe, OEM 16/17 wheel, AD08R, mine.

My NSX is with OEM Type-S suspension with different F/R rake compared to standard coupe.
Tyre pressure set at around 33psi cold at all four corners or F/R = 32/36 psi depending on the conditions.
Something that I felt may not be the case for you and vice versa.
I drive my NSX almost every day throughout the year so hot/cold/dry/wet conditions.
Covered about 160K miles in different driving conditions (UK/Japan).
Used to carry out test driving or on track a lot (multiple NSX + different make/models).
I know how the tyres are being tested at the manufacture.
I have respect to tyre engineers.

As it was my first time driving PS4, I compared it with my NSX (but on different OEM wheel setup, PS4 on 17/17 whereas my AD08R on 16/17) back to back on the same day through the same route.
Jumping into the other car straight after the other so good comparison apart from different tyre size.
The Car #2 was driven a few days after the #1 was returned to the owner so not driving on the same day back to back but my feeling was still fresh.

First, you will need to play a lot with the tyre pressure with PS4, more so than the AD08R.
AD08R seemed to have wider window than the PS4 when it comes to the sensitivity against the tyre pressure change.
I think partially this was down to the fact that the PS4 was still fairly fresh after being mounted on the wheel.
Even with the same tyre size and pressure between Car #1 and #2, just pushing the sidewall with your finger tells you something.
PS4 is really soft though I didn't measure the actual tyre size so please use above info as a reference only.
Same tyre size doesn't mean the same actual size among different tyre manufactures.

I didn't measure the tyre weight so no idea on the difference between PS4 and AD08R.

As it was very hot dry summer day, I started with 33psi (2.3kg/cm2) cold at all four corners.
Very comfortable (ride quality, noise) on the straight and seemed to minimise the vibration from the rough road surface.
However, when doing U-turn using the very small roundabout, as soon as you load the corner, you can feel as if the tyre is squashing/recovering at different rate throughout the roundabout due to changes in load and road surface.
Please note that this is very small roundabout so the speed is at very low range yet you would feel the changes in the rate.

If you on purposely change the TH pedal angle in the middle of the roundabout to alter the load and speed, it was uncomfortable as I couldn't tell what's happening at the rear....
Not easy to tell in words.... It's not sliding because it's at such low speed.... More like you have wobbling hub bearing.
You won’t get this feeling with AD08R.

So, changed the tyre pressure to F/R = 32/36 (2.2 / 2.5kg/cm2) and for me, it felt better but still not to my taste.
I wish I could test the tyre pressure further one day…..

During the cruising mode of 60 - 70mph for like 30min and in between, went through the large roundabout, long upslope acceleration engaging VTEC at the junction, going in and out of mid size roundabout, etc, felt very comfortable, responsive and ease.

So, in summary, I mentioned this to another owner who was looking for the replacement tyre set and to me, PS4 felt like very good candidate for owners doing mainly street driving with long journey and put comfort above the max dry/wet performance.
I think majority of the owners are in this category.
AD08R feels more shifted towards the performance with the trade-off of comfort and the cost.

If I can find the PS4 for my front, I would love to try it next time on my NSX as from time to time, Michelin is offering very good deal on their tyre range and at one point, much cheaper than the AD08R.
Also, probably much easier to source PS4 than AD08R as quite often, you have to act many months in advance if you want AD08R at the specific timing.

I think I'm on the 3rd or 4th set of AD08/AD08R at the moment.
One thing I like it is the wider window for the mistake being made by the driver.
Also, it seems to handle very well (wide window) even when the tyre pressure changes dramatically due to weather condition.
It seems to generate the G lat/yaw by its structure and not mainly through the compound and while no-where-near to the feeling/response of the OEM tyre (you can still get them in Japan), one of the best compromise.

For the wet and cold environment, well, it's upto the driver.
On the motorway for long distance under heavy rain in cold winter, no scary moment with AD08 or AD08R even at 1/2 wear.
I think I was bit more nervous with some of the BS tyres under the same condition but it was long time ago.
When I used to use BS tyres, they tend to change its wet characteristic once it past about 1/3 wear point.

I'm interested in BS RE-71R as I used to love the original RE-71 ages ago.
Don’t think it's available in UK yet….
Some of my friends in Japan are using it and while expensive, loving it.
Worn out fairly fast on track but the lap time didn't change dramatically even after many outings…..

Thanks Kaz - very interesting read!


So in summary, in tyres as with most things, everything's a tradeoff and nothing comes for free. Will have to consider whether I'll realistically place comfort or performance higher on my list of priorities . . .


It sounds as though soft sidewalls are a feature of modern performance tyres - perhaps chasing a little ride comfort when suspension is stiff and sidewall height is so minimal on the current generation of performance cars?

I'd agree with Kaz's comments, but one thing to point out is that the PS4 is the "entry level" performance tyre - I'd expect a different outcome if using Cup2s.

What is the latest view on tyres for the NA1 15/16 wheels? very limited choice now.

When I purchased my car it came with brand new Bridgestone Potenza Adrenalin RE002s. Great tyre for the car - lovely and progressive on the track and enormous grip in the wet.

I race cars and have a number of other faster and slower cars, so I'm not looking for ultimate performance, but a decent tyre which steers nicely but doesn't overwhelm the car with too much grip or ruin the ride on the OE suspension - the RE002 seemed a great balance.

As far as I can see, the only alternative in the OE sizes for a tyre which has any kind of 'sporting' credential is the AD008 which is well reviewed here - anyone compared it to the RE002?

One issue - it appears the AD008r is only available in a 'V' speed rating (149mph)? Whilst I dont drive over this speed often, I have seen 160mph on the autobahn in germany with the W rated RE002s.

Thanks...

Over here in NZ the RE002 has been replaced by the RE003:

http://www.bridgestonetyrecentre.co.nz/tyres/car-tyres/bridgestone-potenza/adrenalin-re003/

I can never remember the spec that is required for the original wheels, so hopefully there is a suitable size for you.

I don't have them on my car, but may do when I come to replace the RE-11s that are on there now, although I'll have to change the front from a 215 to a 205 if I go with this tyre.

Edit:

Just looked at the UK Bridgestone site - you have even less choice than here!

Not it sure if you can order in tyres from Japan or the USA - they seem to have much more (some) choices in the correct sizes...

Quick update. I bought some AD08's for my DC2 Integra Type-R and a set of rears for the NSX. Haven't had a chance to fit the NSX tyres, but I've used the integra on a trackday at cadwell so have done some miles on the AD08.

Very impressive tyre. nice steering feel, stiff sidewall but nowhere near as compromised as a semi-slick. fairly quiet on the road (didn't notice a lot of road noise compared the standard road tyres I had on before) and on the trackday they where very consistent in terms of temperature and grip levels. I'm very excited about them for the NSX - should be the perfect combination of being 'sporty' but not too compromised. Will update once I get around to trying them on the NSX.

Thanks for the update.

In the meanwhile, I've spoken to a track guy with his Integra and he stated clearly that semis are quiet on the first miles when new. But with more mileage on them they get noticeably noisier. He said that the difference was night and day AFTER the first trackday in summer or after a serious heat cycle. He was talking about Yokohama semis available back then. Not sure if the AD08 is an exception of the rule or a different tire.

For the NSX fitments I believe they now offer the later AD08R version ... I’ll be updating as my current AD08 are due replacement ... and for those new to AD08’s, on the NSX Ive used them all year round and on track and been very satisfied. Very high levels of grip, good wet weather stability and even wear rates .. highly recommended

Ah, yes, they are the AD08R, sorry I was just using 'short hand' as the 'non R' isn't available anymore. I agree they are a great tyre - any more grip and I think they would overwhelm the standard NA1 chassis (the suspension is very soft! but I like the compliance and its not a dedicated track car for me)

The AD08R isn't a semislick, the yoko AO series (48, 32 etc) are the semislicks. the AD08R is somewhere between a conventional performance tyre and a semislick (larger tread blocks, slightly stiffer construction and softer compound than say the Michelin PS4) I have done a full trackday and maybe 1,000 miles on the integra's AD08Rs and they are still acceptably quiet (unlike the rest of the car!) a semislick or tarmac rally tyre sounds like the wheel bearings have failed in comparison!

Great tyre with minimal compromise (wet weather maybe as they wear, higher than average wear rate) definitely the only real option now for the 15/16 original wheels IMHO. I did enjoy the bridgestone RE002 and managed 5,000miles from the rears which was pretty good - will see how the Yokos go once they are on the car.

Current suggestions on tyres for a '93 with the original 'fat five' alloys? Just for street driving, no winter driving.

For the OEM 15/16 combo (yes, your size info is correct) and not regularly driving the car or not doing many track days, may be Yokohama Advan Fleva V701???
May struggle finding the rear set in stock.

I think someone on here with European LHD model is/was using it with good feedback.

From time to time, I saw concern on the front tyre speed rating (even for the Neova AD08 series) but without knowing how tyres are being tested on the tyre dyno.
Would be surprised if anyone can apply full load spec at the front without heavily modifying the aerodynamics because at the proving ground, you can feel the front getting lighter/lifting at high speed.
Though, very likely the insurance companies don’t know these facts and just go with the rating label.

Revival of an old thread. What are the current choices for our cars?

I'm looking for some fronts - 215 40 17. I have Advan AD08Rs all round currently. Options look slim for our sizes in general, I'm leaning towards the AD08RS.

I would be interested in what others are using.

The available size for the latest Neova AD09 is still very limited for the European market.
In Japan, several owners are happy with it on their NSX.
Despite the semi-slick like tread design, owners are happy with the wet driving.

While I have AD08RS all around, I hate them.
I liked the AD08 and AD08R but never the RS especially once past 1/3 or 1/2 wear.

Wish Yokohama never changed it from AD08R.

Fleva V701 is quite popular among Japanese owners who don’t drive regularly and only for the street driving purpose.
Several owners in US and Europe seem to be happy with it.

Michelin PS5 seemed to be good alternative for street purpose.
S2000 owners are happy with it.

Bridgestone Potenza RE-71RS is very popular in Japan but note how quickly it can wear out as the trade-off for its super performance.
Don’t know the availability in UK though.

Dunlop is also widely used among Japanese owners but I don’t know much about it.

Continental is highly rated among Acura owners and you can find lots of feedback on Prime.
Probably the ffect of NC1.
Unfortunately, couldn’t find the equivalent of Extreme Contact Sport for European market so never tried one.


I'm quite sure there will be people commenting that one should not mix different tyre models let alone the manufactures.
I was one of them long time ago.

However, after sitting in the passenger seat of many cars including NSX driven by the FIA license holders, it was enough to change my view.
You’ll be surprised what they use for their own cars…
I even put mixed tyres on my NSX in the past when there was no size available.
I placed Toyo Proxus on the rear while keeping Bridgestone at the front.

As long as you know what you are doing and the tyre is from well-known company sold under European regulations, you ‘can’ drive them.
You are not racing on street and most likely, never be able to exceed the chassis performance.

So, hope you’ll find something in your size.

I need to start looking for the rears in case I need to replace them some point in early next year.
I don’t know when AD09 would become available for my rear size in UK. May need going with the 255 instead of 245.
