A device for securement of a spare tire and wheel to a vehicle. The device comprises a shroud which covers the exposed portions of the tire, a bolt attached to the shroud and passing through one of the lug nut apertures in the wheel and a nut threadably engaged on the bolt over the wheel. A cable encircling the bolt and passing through the axle aperture of the wheel secures the nut by preventing rotation when a suitable locking mechanism joins the nut and the cable. The invention reduces or eliminates theft of the tire yet provides easy access for removal. The shroud is of rigid construction and may be painted or otherwise decorated to blend with the vehicle's appearance.
