I have a 2021 Z71 Trail Boss with a leveling kit and wanting to know what’s the larger size tire I can put on my truck.

I just saw a ready lift kit that ran 37 x 13s! I imagine there was cutting involved, but it looks badass.

With some minor modifications you can run 35x12.5 on a stock Trail Boss. So with a lift 37s would be totally doable.

2019 TB custom,I am on Cooper 35x12.5x20 (TB stock copy wheels). 1.5 inch Rough Country leveling and 2/3 of the front flaps cut (all 3 mounting screws unaffected). I do get rub fully turned in reverse.

Did you remove the fender liner bracket?

Do you think that if you have would have went with 17x9 or 17x8.5 you would have a rubbing issue still? And where are you still rubbing even after the trimming?
