ABSTRACT:
A small, compact, collapsible three-wheeled truck which can be used to support a flat or damaged tire of a vehicle while the latter is being driven to a repair location. The truck has a foldable ramp which rests flat on the ground while the rear wheels are in slightly raised position, so as to prevent movement of the truck while the flat tire is being driven onto it. As the ramp pivots upwardly into retaining position behind the tire, the rear wheels are lowered into ground contacting position. Simultaneously, an extension attached to the ramp causes a retaining member near the front of the truck to pivot upwardly out of the way of the tire into front retaining position. The tire after mounting rests in a cradle and is prevented from moving forwardly or rearwardly with respect to the truck.
