For the U.S., after talking with my parts guy, it's the same set up for 550xi's with sport. 18" Style 281 with 245/45/18 Dunlop SP Wintersport 3D ROF. I'm probably going to go that route. BMW is being vey competitive. I could go 19" but with a decent price it'll get close to wheel swap-outs over the next 3 seasons.
