ABSTRACT:
A tire changing assembly includes a foot pedal mechanism connected to a connection assembly that includes a coupling for a vehicle jacking device or to a lug nut device. The foot pedal assembly is operated by stepping onto a foot-engaging element and releasing that element after applying forcing that element down. An operator uses his or her weight to force the pedal down and a spring returns the pedal to a raised orientation. The pedal movement is translated into rotational movement or into reciprocating linear movement so a lug wrench or a jack device can be operated.
