Abstract
An air pressure gauge assembly is mounted to the valve stem of a tire or integrated into a wheel rim for continuous monitoring of the tire inflation pressure. The gauge assembly includes a check valve functionally coupled to the valve stem so that the check valve provides the common function of the valve stem, including allowing for inflation and deflation. The assembly also includes a pressure sensor coupled to a visually perceptible pressure indicator on a dial face.
