I have 16' stock sport rims on my 97 1.8q. I would like some tire suggestions, can I put 225/50/16 on these rims? Also, when I get an alignment does a dealer need to do it or can it be done by you local tire dealer? Because it is a Quattro are there additional things that need to be done? Thanks Keith Krzeminski 97 A4 1.8q
