I'm going to put Pilot Sport Cups on a set of CCW's (9" front and 11" rear, stock offsets) and wondering if 265/35ZR18 and 315/30ZR18's will rub?

Anybody tried it? Thanks!

 

265's are too big for the front.

 

Not too surprising. That's a big jump from 235's.

Thanks.

 

I have a friend with 12" rears and 315's and they fit just barely.

 

I have used MPSC 265 on the front, they will rub slightly at full lock.
NJ-GT, has 285 on the front I think 335 on the rear with CCW 10"and 12"rims.
The CCW 12"rear rims with Hoosier 315 worked on my car.

 

so what is the largest MPSC that you can put on stock rims?

 

According to Michelin.com, for stock wheels (8.5 and 11), 235 on front and 315 on rear. (They don't make 245, 255, 305 in 18's) So, pretty much stuck with 235 on the front. 315's apparently can work on the rear if the ride height/camber is set right. (Wheel Enhancement says 315's are long-time back-ordered, so don't be in a rush)

Thanks for all the input guys. Keep it coming...

I go with 245/315 hoosiers and they fit fine! I had some rubbing issues with a passenger on the track but adjusted the aligment a little and the motons and now its fine!
