I run 275/60/15s on 10 inch rims and they clear everything nicely. Don't know about the low profile tires on larger rims. Cnut

I have 17x10 rims with 275/55-17 tires and they are tight. But , that is on a fleetside. For a stepper, I'm not sure if you have more or less room.

I am curious about this aswell. I c-notched the frame and now my 15" rims hit the fender wells. I believe they are 15x10. I had 275's on the rear and 225's on the front and even the 255's hit. It looks like I got about an inch between the box and rim. I am wanting to put 20's on it now and would like to go as wide as possible, but don't know what back spacing would work..

Anybody with a step side and 20's could you post pics please..
