not sure!
How much lift are you going to put on? A 6" lift or a 4" w/a 3" body would be plenty to run 33's on 8" rims. I don't think I could run 10" rims with my 6" lift. Scott Barrett runs 10" rims but he has around 10-11" of total lift. He could get away with 35"s easy if he were to go with 8" wide rims. As far as my 35's are concerned, they were 14.50" wide on 10" wide rims. There was not way, even with 10" of lift that I could have ever went off road seriuosly. The width of your rim and backspacing is what will determine how much lift you will need. Trust me, I waited almost three weeks to order my rims and tires just because I did't know whether to run 10 or 8" rims and how much backspacing to have. I am not an expert by any means on this situation, but I did a lot of research on rims and tires. If you call just about any of the tire dealers in magazines and tell them what you want to run, they will tell you if it will fit. Any other questions, just holler.
Did you check out my pics on the Attica thread? There's a pretty sweet pic of your "custom" running boards, and my favorite fallen tree!
