A tire parameter monitoring system has a plurality of sensor units for monitoring tire parameters, with each sensor unit mounted with a different vehicle tire. Each sensor unit has an RFID tag reader for interrogating an RFID tag securely mounted to the vehicle adjacent the corresponding tire and containing a unique identification code. Each sensor unit has a microcontroller for combining each RFID identification code with corresponding tire parameter signals, and a transmitter for transmitting the combined signals to a receiving location. Received tire parameter signals are correlated with the tire location using the RFID identification code, and driver advisory signals are presented to the driver by a display/alarm unit. Two alternative power supplies are provided. A first type uses a battery and a power management circuit for eliminating power drain when the RFID tag reader is energized. A second type uses inductive power to provide an inexhaustible power source.
