Tire TPMS Valves and Stems in Houston, TX

A Tire Pressure Monitoring System (TPMS) valve stem is the component on a car’s wheel where the TPMS sensor is attached. It functions as a check valve, allowing air to enter the tire and closing when the proper pressure is reached. The valve stem includes a special valve core, often integrated with the sensor. Reusing the original rubber grommet, valve core, or retaining nut can lead to air leaks, so it’s important to keep the original aluminum TPMS sensor’s valve cap.
