ABSTRACT:
The spare tire of a motor vehicle is placed in a holder which (1) can be lifted to or lowered from a storage position under the vehicle, (2) rolled on running wheels to carry the tire to a position adjacent an axle hub, and (3) operated to raise or lower a tire relative to an axle hub. The holder has a pair of horizontal, spaced rollers upon which a tire is carried. These rollers are mounted on a vertically raisable frame which in one embodiment has vertical slide bars slidingly extending through vertical tubular guides mounted on a wheeled dolly frame. Hand wheel operated screws and hydraulic jacks are provided in respective embodiments for raising and lowering the frame supporting the tire. In attaching the holder at a storage location on the vehicle, the upper end of the holder is first attached and then a winch is used to raise the lower end so that the holder pivots to a horizontal storage position under the vehicle.
