ABSTRACT:
A tire jack for lifting a spare tire onto a vehicle wheel includes a base component with a lifting pan superimposed thereon. A rotatable drive shaft raises and lowers a lifting arm, which in turn raises and lowers the lifting pan relative to the base component. On an upper surface of the lifting pan are a plurality of juxtaposed rollers arranged in a concave configuration so as to readily conform to a vehicle tire. Accordingly, a user places a spare tire on the concave roller assembly and raises the lifting arm to conveniently elevate the spare tire onto the wheel.
