  • Patent number: 12012319
    Abstract: A tire and wheel lift assembly for facilitating the removal and installation of wheel/tire assemblies for vehicles includes a rolling frame member that is generally U-shaped, having a center support member and a pair of parallel side support members. A first roller is disposed on a first side support member, and a second roller is attached to a slidable support member so that the rollers are positioned in parallel relation at the same height. The rollers are used to support a wheel/tire assembly, and the slidable support member may slide along the center support member. An adjustment mechanism controls the slidable support member, which can either raise or lower the height of the wheel/tire assembly by sliding the slidable member toward or away from the first roller.
