335/80r20, you will likely need to do a bit of sheet metal trimming to make it clear while steering, and allowing for suspension movement. I can give you a street review, you definitely know you have a big aggressive tire on, but they are not much louder than the continental 19.5" tires that came stock, there is a bit of a shimmy in the steering wheel although I never had them balanced other than beads. My friend balanced his on his dodge and said it actually worked and he is really happy with them now. For offroad he said he had to really air them down, you have to remember they have a 6800lb load capacity...compared to usually 3500lb capacity-ish with a normal consumer grade truck tire.
