It is time to change tires. I was looking at the Michelin Pliot Sport Cup, 225/40ZR18 with an outside diameter of 25.2 inches and the 295/30ZR18 with an o.d. of 25.1 inches. It then came to my attention that Michelin makes in the Cup Series a 265/35ZR18 with an o.d. of 25.2 inches. This would also be a match with the o.d. of 25.2" for the 295's. I would have to buy 10 inch width wheels for the front. My question is what changes in handling would I expect to occur with 265/35ZR18 Cups in the front and 295/30ZR18 Cups in the rear? How would this affect the balance of the car? The 265 fronts have clearance. My current suspension/brakes are GT3R brakes (380 mm front/359 mm rears), GT3R sway bars with TRG adjustable drop links, JRZ Triple adustable racing coil/shocks w/ upper monoballs, the rest of the suspension has been replaced with GT3R components where applicable (lower arms, monoballs, camber adj. etc)
