Anybody Running 275/35/20 (F) or 285/35/20 (R) A/S Tires?

I continue to research the best 20x10 4-wheel set up with A/S tires (and it's for a ZL1).

285/30/20 is too short for the rear, and I worry that 295/30/20 won't clear the front magride suspension with an ET23 wheel.

275/35/20 tires would be about 27.6" tall in front, and 285/35/20 would be about 27.9" tall in rear - would it clear in the rear with ET23?. Thoughts?


(I still would have my OE 20x10 & 20x11 wheels & summer tires for any track adventures.)

I run those exact sizes for my winter tires on OE ZL1 tires; 275/35 on the front and 285/35 on the rear. Works like a charm. Speedo is off by ~1mph at the most. Unsure about your offest of 23 though.

I was hoping to do ET23 square all around, but maybe have to just go with ET35 in the rear.

Use that https://www.wheel-size.com/calc/
I am assuming you want to change wheels, talking about ET? Then don't forget width of the rim also plays role.
Take that tool, put oem wheel dimensions in it - all of them - and find something.
Apex wheels has also good fitment for Camaros if you are buying new rims.

Anybody have pics with 20x10 ET35 on the rear? Does it look ok on a ZL1?
(I want to run 285 A/S tires in rear.)
