Bottom line: Will Michelin Pilots in a 315 fit stock wheels?
I have done archive searches up the exhaust, and want to be sure that a Michelin Pilot Sport 315/35 18 will fit a factory bolt lowered 01 Z06.
I would love to get maximal tire stuffed beneath my ride, but don't want wheel issues.
I'm confident a 275/40 17 will fit the front without drama, but not sure about the rear.
Thanks so much guys, and sorry if this is redundant.
There is a .78 inch difference between the two. If you consider that half of the difference will show on either side of the wheel, you are looking at a .4 inch larger bulge on the inside and outside of the wheel. I don't think it is much of an issue. Sometimes when you allow too much bulge, you actually lose the contact patch.
TireRack lists the rim width range as 10.5-11.5, so there shouldn't be a problem with it slipping off the rim. Someone on here posted a pic about a year ago showing 315s on stock rims and it looked fine, but I saw a Trans Am locally with chrome Z rims and 315s in the back and the sidewalls were REALLY bulged out. He might have had it on a 9.5" rim though. Hopefully someone will post a pic again, because I'll be replacing my tires soon as well and would prefer to go 315.
