    You could get on bigger tires either by cutting your fenders or by running fiberglass flared ones. Other than that, you're not going to get very big. Why not just get a leveling kit? They're inexpensive and easy.

    The biggest you can fit on a 99-07c 4x4 with no lift on the stock rims is 285/75/16... If you use the stock 17s from 2005+, you can fit 285/70/17s...

    Doesn't it ride rough though?

    Not sure if you still plan on doing this, but I had 33X12.5-17's on my truck prior to my leveling kit (not even a t-bar crank), and only had rubbing when backing up and turning to the left or the right. No rubbing while turning and going forward or even turning while braking (still going forward). Weird, I know, but I checked it over and over and over again.
