Internal expanding jaw machines with rim edge shoe can be lethal to nice rims. Permanent imprints of the jaws remain visible after every tire mount/dismount, eventually producing a "ring around the collar" effect. The plate upon which the rim is rested is very abrasive, mostly from left over dirt from previous use of the machine with dirty wheels. The rim edge shoe is supposed to have a nylon insert that never gets replaced. If the machine is also used for steel wheels, embedded shards can do a number on the rim edge. I have had rim damage more than once.
