ABSTRACT:
An anti-steal tire pressure monitoring apparatus includes: a tire valve; a tire pressure sensor and transmitter connected with a tire inflation valve of the tire valve; an inner cap having the tire pressure sensor and transmitter encased in the inner cap and engaged with a valve seat of the tire valve; and an outer sleeve free rotatably engaged with the inner cap; whereby upon tightly screwing of the inner cap with the valve seat of the tire valve to depress the inflation valve to allow the air entering the sensor for detecting the tire pressure, any rotation (counter rotation) of the outer sleeve trying to unscrew the inner cap will be ineffective, since the outer sleeve is free rotatably engageable with the inner cap, so as to safely “lock” the inner cap and the tire pressure sensor and transmitter on the tire valve without being stolen or removed from the tire valve.
