I can say after having my new Team D wheels mounted with new tires and my Blue SVT poweder coated wheels mounted I had NO scratches at all And the Team D wheels were mounted on the "OLD" style tire machine infact the guys did not want to do them till I said lets try just one and see after all what I am going to do to these rims a lil smirch won't matter . If they use lots of lube (LOL I know) and go easy it will be fine or at least it worked for me.. My Powder coated blue SVT wheels I took to wally world as they were the only place open at the time and they had a newer machine with plastic rim gaurds or something I didn't get to watch but they came out with NO marks either ..
