ABSTRACT:
A valve stem cap for pneumatic tires which has a lock mechanism to prevent theft and unauthorized tampering with the valve. The valve stem cap comprises an inner core with a first end adapted for threaded engagement with the valve stem of a pneumatic tire. An outer sleeve is rotatably mounted about the inner core. Annular flanges at either end of the device are positioned such that the inner core and outer sleeve are locked together. The second end of the inner core forms a solid surface which is provided with keyways for engaging a matched key. By rotating the key, the inner core is rotated, which, in turn, causes the threads of the inner core to be rotated into or out of engagement with the valve stem.
