A valve stem for mounting and supporting a tire pressure monitoring assembly includes a flange formed after insertion into the wheel rim for preventing movement caused by forces generated during wheel rotation.

A track for a track vehicle has sensor-receiving cavities disposed therein. Removeable sensors are placed in the sensor-receiving cavities for sensing characteristics of the track during operation.

A method of replacing a sensor in a track assembly for a track vehicle includes detecting, with a sensor problem detector, a problem related to a first sensor, and replacing, based on the detected problem, the first sensor with a second sensor by inserting the second sensor in a sensor cavity of a continuous belt of the track assembly in which the first sensor was disposed.
