Abstract
In one embodiment, there is provided an apparatus for retaining and moving an automobile tire, and which includes a pair of tire engagement roller assemblies and a lever actuator assembly coupled to the roller assemblies. The roller assembly includes a movable base frame and a tire engaging roller rotatably coupled to the base frame, and the lever actuator assembly includes a lever arm, a link arm pivotally coupled to the lever arm along a length thereof, and a retention bar for selectively holding the lever and link arms in a fixed position relative to each other. Longitudinal end portions of the lever and link arms are rotatably coupled to associated said roller assemblies. Rotational movement of the lever arm towards a generally upright position effects inward movement of the roller assemblies towards each other to mount the tire disposed therebetween.
