Nothing fancy. My local tire dealer recommended Mastercraft Glacier Grip II:

This is the first time I've gone with a dedicated winter wheel/tire combo. It was a little expensive up front, but in the long run I think it will save the wheels from damage changing from winter/summer, etc.
I really liked the BBS wheels. Ideally, I would have preferred 19", but figured 18" would be best for winter.
