ABSTRACT:
Portable tire changing apparatus and method for mounting and demounting heavy tire duty tires on a wheel including a hydraulic cylinder having removable shoes for mounting and demounting, respectively. The cylinder is removably fastened to and retained by additional mounting and demounting structures, both of which are compact and anchorable to a wheel hub eliminating the necessity of affixing a wheel and tire assembly to a bulky stand. The mounting and demounting structures utilize wheel hub rigidity as a base to retain differing supporting mechanisms which position the cylinder enabling the attached respective shoe to maneuver the tire beads away from and over a wheel rim flange.
