9" and 18" wheels - tire sizes

[hollyt]

I'm Considering 18 X 9 1/2 front and 19 X 10 or 10 1/2 rear wheels for my 03.

I've found out that a taller tire might conflict with the traction control.

Where can I find tire diameters and sizes that will be close enough to stock to avoid computer and clearance problems.

Will they fit on my car with stock tubs?? I also think that I would like to stick with Runflats, any ideas or recomendations?

Any help would be greatly appreciated

Thanks

I run 20's all around and 35's in front 30's in rear. This diffinately plays havoc with TC. I run in "Competetion Mode" all the time.

I have heard that later models can have the programming changed for wheel and tire diameter. Hopefully someone has that info for you.

I run 18 x 9 1/2 up front with 265x35x18 and 18 x 10 1/2 in the rears with 295x35x18. You should be able to run 19 x 10 1/2 rears with 295x30x19. Doubt that any runflats come in those sizes.

I just put 18 x 9.5 fronts and 19 x 11.0 rears with 275/35/18 fronts and 295/35/19 rears on my '99 C5. Nothing rubs anywhere/anytime and the active handling seems to accept this amount of F/R diameter stagger just fine even while autocrossing. You will be amazed how much better the ride and handling get as soon as you move away from the run flats. Everything tucks up under the fenders just fine.

Thak you for all of you help. I had a heck of a time figuring this out and would never have been able to do it without your help!!

I have decided to go with 18 X 9 1/2 - 275/35-18 front
19 X 10 1/2 - 295/35-19 rear

The best tire I found in these sizes is the BFG G force T/A KDW.

Thanks again for all of your Help!!!:BOW:BOW:BOW
