ABSTRACT:
A method and apparatus are provided for determining pressure within a tire mounted to a vehicle, wherein the tire is coupled to a tire pressure monitoring system including a sensor coupled to a transmitter, the sensor configured to sense tire pressure and the transmitter configured to transmit the sensed tire pressure to a receiver. First, a first tire pressure is sensed. Then, a calculation is made as to whether the sensed first tire pressure is greater than a predetermined pressure threshold, equal to the predetermined pressure threshold, or less than the predetermined pressure threshold. Next, an indication is provided external to the vehicle that the sensed first tire pressure is greater than a predetermined pressure range, within the predetermined pressure range, or less than the predetermined pressure range.
