I'll know next week, but in general I wouldn't really recommend running the wider (18"x8" front, 18x9" rear) wheels for the winter. For snow you want narrower. Now of course the car has xdrive so this is probably a little less of a point, but consider the staggered setup is a sport setup (which is what even BMW calls it) and therefore not intended for mud and snow.
In short, I'm sure you'll live, but wider isn't always better.
