ABSTRACT:
A device for indicating a pressure drop or low pressure condition in a tire detects a pressure drop and makes an acoustic signal in response to the detection of the pressure drop. The device can include a strut for intermittently contacting a wall of a tire, a striker attached to the strut for striking the wheel rim, and a pressure-activated latch for preventing the strut from contacting the wall or the tire when the pressure in the tire is above a predetermined value by holding the strut tangent to the wheel rim.
