i have a harbor freight tire changer (cheap) with 2X4 base. when breaking the bead, the rotors are touching wood. when placing the wheel on the changer proper, i pad the bottom/rotor with abundant old towels. be aware that you COULD damage the rotors, but with a little prevention, they should be ok without taking them off.
