Depends on if you want tall or wide.
275/65/20 will fit. That is 34x10.8x20.

If you go wider, then you need to go shorter.
You cant go taller.

Confirm 275/65R20 fits without a lift or level kit. Use this size myself. No rubbing.

Wow. You sure? What is your metric siZe?

According to some Jeep websites...
35x12.5/20 = 318/60/20
34x11/20 = 275/65R20

Its half an inch higher than a 275/65/20, and only about 2.7% different in revolutions per mile. However, it is far wider, over 15% wider.

It's the wider part that I thought would cause the issues. It isn't turning ona flat surface. It's turning while at a pitch or hitting a bump.

Don't have any straight side shots, and its dark out now. Can get some later if the below don't satisfy you (taken last month).
