C5 z06 wheels tire sizes
I have a 97 standard coupe. When I bought it it had the wider z06 black wheels but the stock coupe tire sizes, 245/45/17 front, 275/40/18 rear. I want to put on some new tires and I'm going with the Continental ExtremeContact DWS (Ultra High Performance All-Season). Continental doesn't have the correct z06 tire sizes, 265/40/17 front, and 295/35/18 rear. They do make this tire in 255/40/17 and 285/35/18. Can anyone think of any reason I couldn't run these tire sizes on the z06 wheels on my 97? I can't think of one but thought I better ask before I ordered the tires. Thanks for the help!!

I have 255/45/17 and 285/40/18 tires on my Z06 wheels. Although they are not the biggest tires (but still bigger than the base C5), a combination that I like is:
Front 255/45/17 26.1" O/D
Rear 285/40/18 27" O/D
These sizes fit on either the base C5 wheels or the Z06 size wheels. I have this setup on Z06 wheels on my '99. These sizes are closer to the base C5 stock diameters than the Z06 sizes too, so it keeps the speedometer closer. (60.7 mph actual shows 60 mph on the speedometer). The stock Z06 sizes (265/40/17 and 295/35/18) are smaller diameter. (58.8 mph actual shows 60 mph on the speedometer) The 255 and 285 sizes keep the front to back diameter stagger good so the active handling/traction control systems are happy.
Some people think the 255 tires will be a little stretched on the 9.5" wide rims. I think there are some tires that are a wider tread than others in the same size. I had some Firestone tires that were quite small (about an inch tread difference) compared with some Sumitomo tires. You might want to check how wide the tires you are looking at for tread width (not just the 255 labeled for the cross section width).
Good luck with your choices.
