I'm getting ready to take some American Racing (15x8.5) magnesium 5 spokes to the tire shop to have some Towel City slicks put on them. I'm probably over thinking this but as a first time magnesium wheel owner I'm nervous as hell about having them get busted or screwed up in the process. I've done some searches and other than no soap (only water) what other do's and don'ts do I need to be aware of to get them mounted? I'm pretty confident in the tire shop I use and I certainly don't want to tell someone how to do their job but I don't want to walk out of there with my wheels in pieces either. Any tips from you guys that have been there, done that?
