Apparatus and method for transmitting data in a tire condition

A tire condition sensing apparatus (14) includes a tire condition sensor (78, 84, 88) for sensing a tire condition and providing a sensor signal indicative thereof. A transmitter (44) transmits a data message having a plurality of data locations for accommodating data. A controller (72) is electrically connected with the tire condition sensor (78, 84, 88) and the transmitter (44). The controller (72) controls the transmitter (44) to transmit tire condition data in selected data locations of the data message based on a parameter associated with the apparatus (14), such as an identification code of the apparatus (14).
