With the 225's you will loose little clearance in the wheel well about 1/2" as apposed to the 205's I have not had any problems from it. The 'D' range tires are rated 65 psi and are well suited for the TT's weight, the reason I went on up to 'E' was in hopes of getting less role resistance and a little better on gas but haven't used them enough to notice a difference from the 'C' that was originally on there.
