In past years, to get the loose rust out of the beads on 21" wheels, I drilled 4 1/4" holes on the inside of the bead at a equal distance; I then inserted a small cable and attached the end to a drill so I could knock any rust loose. I then worked all the loose rust out. I did not fill the 4 holes as they would not be seen when the tires were mounted; then had the wheels powder coated. Never had a problem with the wheels.
