Help with tire size
I am looking to upgrade my wheel/tire combo and I have located a set of 18x9.5 and 18x11 wheels for my C5 vert. My car is lowered on stock bolts. What size tire would work together with this combo? I run the car 99.9% on the street and drive it all year round, of course only when the roads are dry. I currently run 255/40/17 (Nitto 555 Extreme ZR's)and 285/35/18 (Nitto DR's) on the GM Magnesium wheels, which are 17x8.5 & 18x9.5. Also would a 305 or 315 work out back without sticking out and looking foolish? Thanks

They even work well in the wet! We're having quite the wet run here in the northeast, and the car has been driven every day. And thanks for the comments, though I need to take new pics since I've polished the wheels (again)

Those should work great. Some members are running the 315/30-18 rears on their Z06 rims. Don't forget to post pics once you have 'em mounted!

I have 18 x 10 fronts, 11's in rear. I'm running 265/35-18 front and 295/35-18 rears and they look perfect in the wheel wells. The tires sit exactly even with the edge when looking from above. Also, my car is lowered and nothing rubs.

Folks are running 295's on factory 18x9.5's so I am surprised that you didn't go wider with 18x11's. I figured that the little extra width would gain you some extra traction?
