Abstract: A multi-tire vehicle tire monitoring system includes a plurality of tire monitoring units mounted to measure at least one measured tire parameter of a respective tire on a vehicle and transmit measured tire parameter data responsive to the tire parameter measurement. The system further includes antennae for receiving the measured tire parameter data from tire monitoring units within a respectively assigned zone of tires of the vehicle, each zone encompassing a plurality of tires, and communicating the received measured tire parameter data to a data processing unit. Each antenna is fixedly mounted in an operable spatial relationship to a respective assigned zone of tires. A display may be operatively coupled to the vehicle data processing unit to visually indicate to a user a status of measured tire parameters of tires by zone.

Abstract: A tandem tractor and trailer system includes a tractor having a cab and a trailer, each having multiple wheel units, each wheel unit having a mounted tire and a tractor tire pressure measuring device. A first display unit mounts within the cab of the tractor and a second display unit to the exterior of the trailer, each display unit operating to communicate to an operator of the tractor a visible indicia of tractor and trailer tire inflation pressure status, respectively, based upon pressure measurements of the tractor and trailer tire pressure measuring devices, respectively. The second display unit may mount to a forward end of the trailer at a mounting location operatively visible by differentiated colored light emission through a rear view mirror to the operator of the tractor during operation of the tractor and the trailer.

Abstract: A multi-tire trailer and display system includes a trailer and a tire status display unit externally mounted to the trailer and operative to communicate a visible trailer tire inflation pressure status indicia, the display unit mounted to a forward end of the trailer at a mounting location operatively visible to an operator of a tractor during coupled operation of the tractor and the trailer. The display unit has a display panel operatively illuminated for visibly communicating the inflation status of the trailer tires and the display panel may communicate changes in the inflation status of the trailer tires by differentiated colored light emission. The display unit is at an elevated mounting location at a forward end of the trailer so as to be visible by means of a rear-view tractor mirror to an operator of a tractor coupled to the trailer as well as ground personnel.
