Abstract: A wheel lock is disclosed which comprises a pair of tire width adjustable hooks members which are slidably positionable for tire diameter adjustment and locking. A pair of chocks are also provided for meshing with an inside rim surface of a wheel to be locked which prevents the device from rotating as a tire. The width adjustment is only accessible when the device is not installed while the tire diameter adjustment also serves as a keyed locking mechanism for the device. The device is constructed of lightweight tubular components and is particularly adaptable for use on trailers, motorcycles and ATVs.
