I don't need an all-season tire for the M3, but if I did, no question this is going to be the one to buy. From what I've heard, the dry performance of this tire is equal to or better than some other high end summer tires (i.e. Conti DW for one). Michelin is basically creating a new class of tire -- extreme performance all-season -- it would appear. It's going to be interesting to see the test results.
