Mitch, could be, although I lowered the rear an inch right when I tried these two sets. The 315 Rival S just didn't feel as glued down in the rear, the front felt good (with the Bridgestones). When I had the alignment done I actually had an even taller rear tire, the 305/30/19 Hankook. Wade I think right now with the current crop of 200TW tires you don't need wider than the 275 RE71R, but this tire war will do nothing but escalate. Someone is bound to bring out a wider super sticky tire. If I were to build a car from scratch I'd aim for a 18x11.5 315 front and a 18x13 335 rear, and I'd run the Rival S on it for now...
