There are some other factors to think about. I plan on putting 33x10.5 BFG MTs on my truck and know they will fit and I just have a 2" bodylift and front leveling spacers. I know that they will fit with 15x7 3.5 backspace so i will likely get 15x8 with 4.5 backspacing when all is said and done. What width were you looking at? 10.5s maybe but 12.5s are a little doubtful without trimming or doing some more thinking about wheels and backspacing. Your best bet is to try some on if you get the chance, everyones truck is a little different.
