With a 2" body lift (as you have) 33's will easily fit. The only thing you may have to do is bend the splash shields in the forward wheelwells forward slightly and trim the front bumper end-caps a little. The splash shields are at the very front of the front wheelwells and they can be bent by hand.

The rims I have are 15x8, 3.75" backspacing, -19 offset.
