I have the same size wheels and they are TSW's. If you go lower than 2.5 you will have rubbing in the rear with a tire wider than a 215 and higher than a 40. the front has a little more room, but If you wanted to say go extreme like 3" than you cant get a bigger tire than 205/40-17's and those are TIGHT!!(fit that is ) G/L and nice wheels
