I am currently reviewing the Tirerack site for immediate purchase of wheels and snow tires for my 2001 330i sport. Is there much difference in quality between Borbet, Mille Miglia,ATP, and Sport wheels? Also the site is only showing me 225/45r17 tires. Can't I use 205/50r17 like the non-sport 330i as these would probably be better in the snow?
