is anyone out there running 225/45's on 18" rims. I just bought a set of winter tires on s line replicas. I got a great deal, but now I hear some rubbing as my suspension absorbs bumps. The previous owner supposedly had this same set up on a 01 a6 sedan. I have a 03 a6 avant. Did I get screwed on this deal? This set up looks amazing and I hope I can use these. any ideas? wheel spacers?
