I'm brand new here but can't seem to find this info (at least consistent answers) anywhere so thought I would try my luck here.

I am looking to get a second set of wheels for a set of snows for a 2007 S6. I have yet to drive this car in the winter & hear snows are generally a very good idea. What I am looking for is a compatibility list (or even just the existing offset for the OEM wheels I have) and if I can take sets off regular A6s or RS4s and turn them into snows.

If anyone has any feedback / recomendations on tires as well I would appreceiate it. I'm currently looking at a set of Bridgestone Blizzak LM-60s.

Thanks!
