Abstract:

A tool for assisting in lifting and positioning a tire and wheel assembly into position for installation on or removal from a vehicle hub comprising a pair of arcuate base members, which together form a cradle for receiving the tire. The arcuate base members terminate in a pair of pivot members with beveled points contacting the ground surface for a secure steady lift. Each of the arcuate base members is provided with a lifting member disposed on the proximal end of the arcuate base member so as to support and steady the wheel and tire assembly in a substantially vertical position as it is lifted onto the hub. Handle means for lifting of the tire and wheel assembly may be folded so as to provide a compact configuration for storage.
