Yea, you can put 31x10.50 on the stock wheels, that's what i run with 4.5" lift, they do look really small with that much lift, but with 3 you be perfect. Stock rim i think is 7" wide so tires only 4.5" wider then the rim, it would work good. I think that most of the people who got 31's are running stock rims, it's when you want to go to 33x12.50's you got to get 8" or 10" wide rim.
