Abstract
A vehicle wheel includes a tire that is sealed to a rim. The tire is inflated with air to a desired pressure level via a valve assembly. The valve assembly includes a valve stem with an elongated body having a central bore extending longitudinally through the body. A pressure sensor is mounted within the bore to measure the air pressure within the tire. A ball and plunger valve member is engagable and disengagable with a valve seat formed within the bore. A central tire inflation system uses the pressure sensor to monitor the tire pressure for each wheel on the vehicle. When the pressure sensor measures an air pressure in the tire that is below a desired level the central tire inflation system inflates the tire with air until the desired pressure is achieved.
