You will have less sheetmetal interference with 33's. If you are not affraid to cut up your fenders then you can fit 35's. I run 32's with a 21/2" lift, and I don't rub that I can tell. You could also install a 1" zero rate add a leaf from Offroad Desigh when you install the 2" springs, and clear 35's better if you want to run 35's.
