Zusammenfassung:A tire wear detection device includes a wear detector embedded in a tread of a tire, a sensor unit arranged on a wheel, and a receiver unit arranged on a vehicle body. The wear detector includes a piezoelectric element and a resonance circuit, which generates a radio wave signal from a voltage signal generated by the piezoelectric element. The sensor unit transmits through wireless communication a pressure data signal indicating an internal air pressure of the tire, generates a wear data signal indicating a wear state of the tire based on the received radio wave signal, and transmits through wireless communication the wear data signal. The receiver unit receives the pressure data signal and the wear data signal from the sensor unit.
