Default 345/25/21 Tire?

Anyone running this tire on a 21x12 rim on a base C8? Any issues?

Didn’t realize you can run the C8Z06 tire on a narrow body C8, that’s impressive.

There are people running 345 on 18" wheels. Will depend on offset I would think. X25 has run 345/35/18 which is 0.3" smaller than the 345/25/21 you mention (of course manufacturer variation will apply). This should be feasibly but ride height and offset will be extremely important.

Yep, that's the exact size wheel and tire I'm running on the back of my Stingray.
