Re: big tires

I've got 31x11.5's on mine, pretty good clearance, and I've heard guys running 12.5's with no issues

Re: big tires

here is my 315/35/20 on my truck before I tubbed it. I think with a little bit of lean, the tires would have rubbed the wheel well.

Re: big tires

I'm pretty sure you can't fit a 15x15 wheel without mods. I think a 10" wide wheel is about the max, at least with a decent tire. You could maybe fit an 11 or 12" wheel with the right tire size, but still may have some rubbing issues.

The 15" wide wheels may fit without notching the frame, but will require bed mods. Hopefully someone with more knowledge will comment.

mini tub to bed is required to fit tire, but no c-notch!
