Abstract: The present invention provides a small vehicle wheel locking assembly which may be quickly installed over one or more wheels of the unit to be protected, and then locked or bolted to the truck or to an adjacent structure. The preferred embodiment comprises basic top and bottom enclosures in which the wheel of the mobile unit may be placed prior to closure of both assemblies into a box like enclosure. One side of the bottom enclosure is hinged to permit rolling the wheel into the enclosure, and one side of the top enclosure is hinged to aid in sliding the enclosure over the top of the wheel. When closed, the upper subassembly is interlocked with the lower unit and secured with a shielded padlock. The lower subassembly may be secured to the bed of a pickup truck, or to a stationary object. In this manner, the wheel is immobilized against rolling and sliding, and access is denied to all points of wheel or tire disassembly.
