<p>PROBLEM TO BE SOLVED: To efficiently replace tires without requiring to register identification codes of the respective tires in replacing the tires by registering tire identification codes of a plurality of tire sets in a receiving part for monitoring a tire air pressure of the respective tires and a storage part of this receiving part. SOLUTION: This device has a sensor unit 10 and a monitoring unit 12. A tire air pressure sensor 16 of the sensor unit 10 outputs a signal according to an air pressure to be supplied to a transmitting CPU 18. A transmitting circuit 22 transmits a detecting value and a radio signal containing a tire identification code from a transmitting antenna 24. While, the monitoring unit 12 supplies the received detecting value and the tire identification code to a receiving CPU 36 to be compared with a tire identification code preregistered/prestored in a nonvolatile memory 38 to judge which position tire it is to judge the existence of abnormality of tire air pressure on the basis of the received detecting value to thereby efficiently replace tires.</p> |
