Tire Size Question - Again
I've finally gotten the rims that I want for my 2000 Vert in an attempt to avert the $76,000 price tag that I saw on a very nice C6 Vert at the dealerhship today. The plan has been to upgrade/mod to stay away from the monthly payment demon.
I just purchased a set of chrome C6 Z06 rims and I'm having difficulty finding the "stock size". I'm not interested in mini tubbing or spacers of any sort. The rim sizes are 18x9.5 for the fronts and 19x10 for the rears.
I've decided on Hankook V12s.
What size tires do I need?

From what I can find, C6 Z06 wheels come with 275/35/18 front and 325/30/19 rear. Hankook does not make a 325/30/19, so you may need to look at different tires. Nitto Invo do come in that size, or Bridgestone and Goodyear. As for the spacers, I am not sure if you can get away from that because of teh offset on the C6 wheels. You most likely will have an issue with the inner fender well and a rub.

Not to hijack your thread, but interesting set of lights in the front brake cooling ducts. Any info on them - did you do them yourself, buy them already made, etc.?

If you look at tirerack.com and put in the year vette ex. 2007 C6 coupe it will show you the correct tire side and what tires are available in that size. It will list both front & rear pairs. Its a great site for getting tires at a very good price. They deliver in a few days and you can search on thier site for tire shops in your area that will mount & balance the tires. You can make an appointment & get a price quote online. Its very easy. Good luck and post pic's when you have your new shoes on.

A 19x10 wheel is too narrow for stock C6 Z06 sized tires. The 325-30x19 that is the OEM size tire for the C6 Z06 is fitted on a 19x12 wheel.
Obviously the wheel that you selected is an aftermarket replica wheel, that happens to be stock C6 sized. In that case, you need a 285-35x19 for the rear. You can go to a 295-30x19 if you prefer. The issue that you have not mentioned is the offset. Are the 19x10 wheels C6 or C5? There is a difference - C6 rear offset is 79mm, C5 offset is 63mm.
The C6 79mm offset means that the wheel is too far into the wheel well, and might possibly rub on the frame. Some people have used a small spacer to push the wheel out.
If you are set on this wheel and you don't want spacers (I wouldn't), you can buy that exact size and style wheel in a C5 fitment (63mm offset).

I neglected to mention that they are REPLICAs. The offset is supposedly 120.65.
The forum vendor that sold them to me recommends:
Hankook V12s
275/35/18
305/30/19
He states and I quote, "that will give you a very aggressive stance." I'm lowered on stock bolts.
The rims again are
18x9.5 Front
19x10 Rear
Do you agree with the recommendation of the vendor?

I have a lowered (about an inch) '02 Coupe with Cray Scorpions 18x9 (F) & 19x10.5 (R) that had the same size tires you're now considering. The fronts (275/35/18) stuck outside the wheel well maybe a 1/2". Just a week or so ago I had new Michelin Pilot Supersports installed & went with 265/35/18 up front & stayed with 305/30/19 in back. The front tires are just a tad outside the wheel well now, and looks much better to me.

To verify before you pull the trigger - ask the vendor to verify that the back wheels are C5 fitment not C6 fitment, as I indicated the difference in my first post.
Finally - if the vendor is not sending you the wheels mounted and balanced as a package, I highly recommend that you try a "dry fit" of the wheel. This means mount the wheel on the car before the tire is put on it. Most wheel manufacturers and vendors will accept a return of a wheel as long as it has not had a tire mounted on it.
When the wheel is on the car - note the relationship of the wheel rim edge relative to the lip of the fender. If it is way back from the edge, it is the wrong offset. If it sticks out, the tire will stick out even more than the edge of the wheel. Also - I believe the wheel offset will be stamped on the inside of one of the spokes. Good luck!
