Abstract: There is disclosed herein load simulating apparatus for use in applying a load to a mounted and inflated wheel/tire assembly in order to insure proper and complete seating of the tire bead on the vehicle rim. The load simulating apparatus of the present invention incorporates a plurality of pivotably mounted driven rollers which are operable to move into engagement with the peripheral tread portion of the tire and to accelerate same while applying a generally radially inwardly directed force thereto so as to simulate the loading on the tire typically encountered after the wheel/tire assembly is mounted on a vehicle. Preferably, the load simulating apparatus of the present invention will be incorporated in a wheel/tire assembly line and located prior to the balancing machine so as to insure proper and complete seating of the tire bead before the assembly is balanced.

Abstract: An apparatus and method for assembling wheel and tire units onto a vehicle as it moves along a conveyor. The apparatus includes an arrangement for centralizing the vehicle relative to the conveyor, orienting the hubs of the vehicle so as to receive a properly oriented wheel-tire unit, an apparatus for orienting the wheel-tire unit and means for mounting the oriented wheel-tire unit on the hub and for affixing the thus mounted wheel-tire onto the hub.

Abstract: A mechanism for lifting wheels from a conveyor and positioning them in a wheel soaping mechanism. Also included is a device for rotating a lifted wheel through 360.degree. for presentation to a spray nozzle for soaping the wheel. The rotating mechanism is adapted to rotate each sequentially presented wheel in a direction opposite to that of the previously presented wheel.
