The assembly includes a hub having an inner surface, an outer surface and a peripheral edge. The hub has a plurality of apertures extending therethrough. The number of apertures equals the number of threaded bolts. Each of the apertures is positioned for selectively receiving one of the threaded bolts. A plurality of arms each have an attached end that is attached to the peripheral edge and a free end extending outwardly away from the hub. Each of a plurality of gripping members is pivotally coupled to one of the free ends such that the gripping members are selectively positionable in a stored positioned adjacent to a side wall of the wheel or in a gripping position abutting threads of the wheel.
