As to avoid any TC or AH issues what should I run up front? I have a C6 with the widebody rear but standard front and I've been told if I don't have a certain size up front I could get some random AH and TC errors. I have 19 rears and 18 fronts. Thanks.

I have 275s 18" on the front.

Those 275-18's fit ok with the stock fenders up front?

here is a stock 275 or 18x9.5 OEM Z06 wheel. The tires stick out a bit but didn't both me as I went full widebody a couple months later.

With my 345/30/19 rears I have 275/35 on 18X9.5 CCW's with offset for stock C6 fender and Z06 brakes.

The width of the tire is irrelevant. The height is what will matter with active handling. There are people who have run the stock front 245 up front and it works fine with a 27.5" tall rear tire (the height of a 345/30/19).

Thanks, I looked up the tire diameter and they are only about a 1/10th of an inch different so I should be good. I'll just buy the 275's when I need to replace the 245's or I put the ZR-1 fenders on it.
