Bridgestone has come out with a new snow tire that will be available in Sept. or Oct. which is an H-rated, unidirectional, studless winter radial tire for import sports cars and touring sedans. It is called the WT-05. Call Matt (He's big on BMW and M3's in paricular) at the Tire Rack (1-800-428-8355) for all the info. I.m getting a set for our new M3 in the fall. It is available for the 17 inch wheel. Good Luck.
