They ride great. The side wall is .3 inches higher, so there's a little more flex I guess. The overall diameter is off by .6 inches, which throws off the speedometer by 1.3mph at 60mph, not a big deal. I want to say that they are a little quieter on the freeway than the Michelins, but I'm not entirely convinced that I'm not imagining it. The biggest difference is in the appearance. They look really aggressive from the rear and fill out the fender wells better than the 255s, plus that price at the Tire Rack is incredible.
