I just wish I had a proper wheel and tire shop around me. I have one that I mostly trust to do the OE wheels although they haven't worked on any 20" wheels of mine, only 18". When I brought my M5 with its three-piece Fikse wheels the managers all got this horrified look on their faces and they refused to do the work. Can't even get an alignment.
