Abstract
A tire differentiating system ( ) is employed to differentiate tires ( ) in a vehicle ( ). Each tire includes a sensor ( ) which communicates with a receiver ( ). In a first example, when a tire ( ) is inflated above a high pressure threshold, a flag bit is stored in the sensor ( ) identifying the tire as a rear tire ( ). If a rear tire ( ) drops below a low pressure threshold, a warning algorithm is initiated to warn the driver. In a second example, the sensor ( ) is a transceiver with an RF detector circuit having an identification code. A RF transmitter ( ) is located proximate to each of the respective transceivers ( ). The receiver ( ) sends a signal to each RF transmitter ( ) which generates a RF signal that is sent to the transceivers ( ). The transceivers ( ) then send a return signal including the identification code back to the receiver ( ), identifying the tire ( ) at the location.
