ABSTRACT:
A method and apparatus for demounting tires from wheel assemblies with a hook assembly and a prying foot. One tool has two holding hooks that grasp the tool to the wheel and a foot that is attached to the holding hooks, and a bearing pivot point that allows the demounting tool to easily and safely remove the tire from the wheel. The tool can be used for all types of tire and wheel types. One tool is for large truck and trailer tires and a second too is for light truck, trailer and automobile tires. A third tool is designed for low profile, stiff sidewall tires and includes a telescoping structure to raise and lower the dual hooks. A forth embodiment is for demounting a first and second bead using a fixed pivot hook, sized prying feet and a telescoping assembly for pulling the bead from the wheel assembly.
