1. A tire parameter sensing system for a vehicle having at least one tire, the tire parameter sensing system comprising:

  • a tire-based unit associated with the at least one tire for sensing a parameter of the at least one tire and for transmitting a tire parameter signal indicative of the sensed parameter;

    a transceiver device located on the vehicle for receiving the tire parameter signal and for transmitting a relay signal indicative of the received tire parameter signal;

    a vehicle-based unit mounted on the vehicle in a location spaced away from the transceiver device, the vehicle-based unit adapted to receive both the tire parameter signal and the relay signal; and

    an indicator coupled to the vehicle-based unit for providing an indication of the sensed parameter of the at least one tire, the vehicle-based unit controlling the indicator in response to receiving at least one of the tire parameter signal and the relay signal.
