I'm on my third set of brakes and need to install a third set of tires at 10,000 miles. I'm not complaining, I've been on the track quite a bit.

Anyway, I want to install Michelin Pilot Sport Cups, but they only come in larger sizes.

The car comes with:

215/45ZR18 in front with 7.5" rims.
275/40ZR18 in the rear with 10" rims.

The Pilot Sport Cups come in:

225/40ZR18 requiring a 7.5-9" rim,
285/30ZR18 requiring a 9.5-10.5" rim or
295/30ZR18 requiring a 10-11" rim.

These tires are not as tall, but certainly are wider. Will they fit?

 

It all depends on the offset of your rim, but your not going that drastic so it should work. I would also suggest the BFG k/d over the pilot. Pilots take for ever to warm up and are terrible with any temp under 60. Pm me if you have questions.

I'm assuming you're looking for a dual-purpose street/track tire. The PSC is pretty extreme for the street, you have to be VERY cautious in cold or wet conditions, plus they tend to "die", grip-wise, after x number of heat cycles, regardless of tread remaining. I just mounted 225/40x18 and 275/35x18 Toyo RA-1s on my Modena, and in my opinion this is the best street/track tire on the market. Great track performance, yet usable on the street, nowhere near as heat-cycle sensitive as the PSC.
