Tires were fine except they rub the rear of the inner fender well on the engine side when you turn all the way to the lock. Not likely something you would do on the drag strip. No issues with either rear or front on a 10 mile drive around town. Both wheels were the ones Weld recommended for a 2012 ZL1. I had them in the garage so I tried them. Here are the sizes:

Front: Weld RT-S, 17x5 with M&H 4.5/28.0/17 tires
Read: Weld RT-S, 17x9 with MT ET Streets, 295/45/17

Thanks for the pics, great to see.

Car stock has shorter tires so maybe 27's would be better? Also I'd be curious if a 5mm spacer would make the fronts fit better.
