The 235's look pretty good to me. Do they rub at all? If the rims are 15 x 7's, that's plenty of rim for a 235. Your car looks really good with the Cragars.
No, they don't rub, but they balloon quite a bit. The fronts are 14x6, I haven't looked at how wide the rears are yet, but I assume they might also be 15x6. So, if I get another two 15s, I'll get 15x7s and swap front and back.
