Abstract: A selective optional lug adapter is to be mounted on a securing rod assembly that is held in place by a pair of clamping plates which are selectively bolted in place on a pivot tube supported on a base so that a small wheel rim can be held stationary while the tire or the rim is changed (i.e. removed and replaced) in a matter of minutes. Furthermore, the entire device can be disassembled into its major parts for storage, and adapters for different openings in the small rim can be changed or omitted.
