can someone pls explain to me why most run 245/40 18 Front & 275/40 18 Rear instead of 265 / 40 Rear?
compared to the original 225 /45 & 245 / 45, Height wise 245 / 40 is about 3.5% smaller and 275 / 40 is almost similar.
However, 265 / 40 is about 3.8% smaller than 245 / 45
me thinking that using 245/40 & 265/40 is kinda keeping the ratio between front & rear better than the 245/40 & 275/40 combo
nothing related to handling etc just pure proportions
am i not understanding something?
Thanks

I am running PS2 265/40/18's. The last time I looked at Tire Rack and talked to Reggie at Tire Rack one of the choices was Michelin Pilot Sport PS2. The spec wasn't listed, only that it was OEM for Porsche.

I agree that the 265 looks a bit more stretched on the 10" than we are used to here in the US, but it is a more popular look in Japan. The 265 also keeps the stock stagger of the rear wheels being 20mm wider than the fronts. 245/275 will understeer more at the limits.
