Sorry if this sounds like a daft one, I have read the sticky tire size guide which is very useful. I haven't got later style OEM rims so not entirely sure if I need exactly the same size tyres.

I have a 1991 NSX which has OEM 15/16 rims and I have recently brought some new Gotti split rims 17inch rear and 16inch front.

The wheels came with tyres which need replacing and aren't on the rims.

The rear tyres when placed next to my OEM ones appear the same effective size which is fine. However, the fronts seem bigger. I am going to stick with the same size on the rear but should I change the size at the front?

Does anyone have any suggestions? Will it cause a problem?

OEM Fronts 205/50R15 86V

New Fronts 215/45ZR16 86W

OEM Rears 225/50ZR16 92W

New Rears 245/40ZR17 91Y

Also should I stick with 33psi at front and 40psi at rear??

Cheers

Thomas
