C6: Who's Running 18x10.5 Front Wheels?
If you have a C6 and are using 18x10.5 (62 mm offset) C5Z wheels in the front, what rubs at full lock: the tire on the fender, the wheel on the control arm? Or is something else rubbing?
What offset would minimize the rubbing: 56 mm or less, or 62 mm or more?
The reason for these questions? I'm trying to determine if I can run a 295/35-18 tire on the front wheels. There's a picture of a C6 with those tires on the DRM (Doug Rippie) web-site with those front tires. How do they do that?

The largest tire I've seen on OEM front wheels (18x8.5 w/56 mm offset) is 275/35-18. My thinking is that a 295 tire will stick out an addition 10 mm. If the offset is increased to 62 mm, that moves the outer rim inboard 6 mm. The net "stick out" is 10 - 6 = 4 mm, or 4 mm outboard of the 275/35-18 tire. Of course, the inner tire face has been moved 10 + 6 = 16 mm inboard. That is, I believe, the source of rubbing.
But, how much does that rubbing reduce the turning radius?
