A tire pressure monitoring system ( 12 ) for a vehicle ( 10 ) includes a speed sensor ( 38 ) generating a speed signal indicative of vehicle speed, a timer ( 44 ) generating a time signal, a warning status memory ( 26 ) having warning statuses therein. The system further includes a plurality of rolling tires in respective rolling location. The plurality of rolling tires ( 14 a), ( 14 b), ( 14 c) and ( 14 d) have respective rolling transmitters ( 16 a), ( 16 b), ( 16 c) and ( 16 d). An auxiliary tire ( 14 f) in an auxiliary location has an auxiliary transmitter ( 16 f) that generates an auxiliary sensor transmission signal. A controller ( 22 ) is coupled to the rolling transmitters, the spare tire transmitter and the warning status memory ( 26 ). The controller ( 22 ) receives the auxiliary sensor transmission signal. When the speed is greater than a predetermined speed and, when the time signal is greater than a predetermined time, the controller associates the auxiliary sensor identification to an auxiliary location of the warning status memory.
