Do you guys think there would be a noticeable difference in going to a 255 up front instead of the 265? I'm looking at the TA KDW 2, but the largest size they come in is 255/40/17. :-? :-? :-? :-? :-?

The 10mm difference reported above is slightly wider than your front tooth, to give you some perspective.
