Bottom line: Will Michelin Pilots in a 315 fit stock wheels? - Z06Vette.com

VETTEST · 03-24-2005, 06:32 AM

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.

Cheers,

Greg

Yes. but the ideal size rim would be 11in.

So does this mean that it could be dangerous?
Will a tire slip off mid turn? :eyes:

Thanks for the answer... But it is a tad scary! :eek:

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.

That my friend is what you call PHOTOSHOP skizills...

Those look like 335's. Pretty damn wide. Does anyone have good "unaltrered" pics of 315's on the back of Z06's? Considering getting those too....295's look narrow to me for the vette.

Vettest, if you want those photoshop size tires, recommend a 12" wheel for the rear. AND, a little process called "tubbing".

I've got Michelin PS's 315/30-18 on 10.5 Chrome Z06 Motorsport wheels. They fit fine, no rubbing.

In fact my BFG DR's are the same tire size, but they actually measure all most 3/4 of a inch wider than the PS's and they don't rub either.

Same here, I got 315-18-35 PS's on the back on stock rims, and they fit fine.

I'm no expert on handling, but to me they felt about the same as the GYF1sc...

I took some pictures of my car back when I got them installed, but they suck (the pictures!)... Here it is anyway, in case you still want to look at them:

I forgot to mention that I also have the car lowered to the max using factory bolts.

Hey Geoff!
So, how would you compare the PS2's to the F1's in straight ahead traction & cornering stiffness??
Thanks! Ron

So is that an ok setup to run with then 275 PS on the front 315 PS on the back ?

I need tires soon so I am looking at all the options.

I thought I read that if you put larger rears on you should also use larger fronts to prevent oversteer.
