ecu the data is transferred to a telematics unit the system preferably deploys a sensor module for a group or region of tires a separate first display within the cab of the tractor communicates the status of tractor drive and steer tires to the operator while a second display unit mounted to the trailer communicates the status of trailer zone tires to the operator visually by means of a rearview mirror the sensor s from each tire within a group or region transmits data the grouping of tires may be for example the tires of the tractor and a second or third group for the trailer an under inflated tire on either the tractor or the trailer may be identified and a warning provided to the driver through first and second display units such information allows for corrective action to be taken before it becomes a safety issue running with properly inflated tires increases fuel economy and decreases treadwear properly inflated tires provide better vehicle handling and increased tire durability the system eliminates the need to conduct a teaching procedure that registers and registers with each tractor trailer change each sensor and its wheel position from a tractor and trailer in the ecu the system eliminates the need.
