1. A tire condition sensing apparatus comprising:

  • a tire-based sensor for sensing two relative rotational positions of its associated tire relative to the earth'"'"'s horizon as the tire rotates and providing first and second signals indicative thereof;

    transmitter for transmitting a tire identification, tire condition information, and a processing time delay value in response to each of said first and second signals;

    a vehicle-based sensor for monitoring tire rotation relative to the vehicle'"'"'s chassis and providing a signal indicative thereof; and

    a controller for monitoring the transmitted tire identification signal, the processing time delay value, and the signal from the vehicle-based sensor and associating tire identification with a tire location in response thereto.
