Abstract: An adjustable dual-wheel caddy for supporting wheel assemblies when they are removed from vehicles is described. The caddy includes a U-shaped support having a single movable leg and rollers along the lower surfaces of both legs. A crank handle is provided to manually change the bight of the "U" only in response to rotation thereof. An internal rack is provided along at least a portion of the bight of said "U". A spur gear is rotatably mounted on the movable leg in mesh with the rack and a worm gear is mounted on the crank handle to drive the spur gear in response to manual rotation.
