ABSTRACT:
A self-propelled tire dolly for transporting a tire in a working area for performing tire removal and mounting services by placing the tire on a tire-supporting section which is raised or lowered by a lifting device. The tire dolly is supported by three wheels, and a drive wheel among the three wheels is located at a central portion of the base on the rear side thereof. A steering handle is provided above the drive wheel. Since the drive wheel constituted by a single wheel and the steering handle are located in the center on this side during maneuvering, the tire dolly is easy to steer. The steering handle can be retreated from a fixed position to obtain a working space during tire removal or mounting.
