CCW makes 18X10 and 18X10.5 that will fit a 275/35 without issue. i do not know what the offset is and i doubt they would tell you unless you bought a set.

I have 18x10 SP500's on the front of my C6. I am currently running 265/35/18 rubber but will be running 275/35/18 when they decide to release a 325/30/19 NON-runflat PS2.

My track wheels/tires are CCW C10 wheels 11” x 18” all around and they're setup so each wheel is identical with the same offsets. I run 305/30/ZR18 tires on the front using hub extenders/spacers. My friend runs 315 track tires on the front of his C6. I believe his fronts are 18 X 11 CCW wheels with an offset of 56mm using P315/30ZR18 tires.

The R888 275/40/18 will fit nicely on a 9.5" rim, but you'll need an offset of 69mm, which will give you a stock tire/fender allignment. I figure an offset between 65-69mm would keep everything inside the fender. Stock front offset is 56mm. In order to keep the stock fender/tire allignmet, you need to add a half inch (12.7 mm) of offset for each 1" you add to your rim width.
