Hi All

I currently do not have a lift or a leveling kit but was wondering what the max tire size I could run on 18in rims. I have the max tow package and the tires look tiny. I read online that I could fit 35s with no rubbing or any modifications. The truck is a lease and I'm not 100% certain I'm going to keep it so don't want to make too many modifications.

I haven't done a lot of research on non-ORP trucks, just tossing some thoughts... My Rebel with a 1" factory lift ran 33's stock. From what I've read when seeing if my Dad's non-ORP truck could run those, it should be fine. So I'm 80% confident you could do 33's w/o any work (personally never 100% confident until I see something work myself a few times lol).

I think 35's would be pushing it. They don't even work without modification on the Rebel. You have to level, and even then you still need to trim. Even the KO2's at 34.5" rubbed for me without removing the stock mud flap, trimming wheel liner, etc.

Does your truck have 20in rims? I'm so new to this stuff I'm not even sure if that makes a difference or not as my truck, with the tow package, has 18in rims.

My Rebel came stock with 18". Really all that should change with a larger wheel and the same tire is less sidewall.
