I'm about to mount the tires on my magnesium halibrands. I absolutely REFUSE to take them to one of these tire shops because the guys in that back don't give two craps about gently handling other people's possessions. I'm wondering what to use to protect the rim from marring when using the tire irons? I've done numerous steel wheels in the past but, with those you don't have to worry about marring the surface of the wheels. Any help would be appreciated. Thanks!!
