I have aftermarket rims with snow tires - I didn't want to use BMW run flat snow tires because the run flat tires that came with the car were terrible. The tire is embossed with the words "mud and snow" and I felt this should be taken as a warning not to drive in mud or snow. So I bought winter tires and Bridgestone Blizzack rims. Either way, these rims require a hub ring and fit like a glove.
