Abstract
A tire pressure monitoring system (12) for a spare tire of a vehicle (10) includes an indicator (52) and a timer (44) that generates a first time signal corresponding to the time the spare tire is used as a rolling tire and a second time signal corresponding to a time the spare tire is stowed. The temperature sensor (34) generates a temperature profile and a controller (22) that is coupled to the indicator, the timer, and the temperature sensor generates a spare tire warning signal in response to the temperature profile, the first time signal, and the second time signal.
