ABSTRACT:
A tire pressure monitoring system for vehicles characterized by a plurality of tire pressure sensors for sensing pneumatic pressure interiorly of the tire, a plurality of transmitters connected responsively with the tire pressure sensors and adapted to be energized when any one of the tire pressure sensors indicates a low pneumatic pressure within one of the tires; at least one receiver responsively disposed with respect to the transmitters so as to be energized by a transmitter when the transmitter is energized by the tire pressure sensor and a warning means, including a buzzer and a light, disposed in the operator's cab for conveying the warning to the operator when a low tire pressure is sensed, the warning means being electrically connected with the receiver, or receivers, so as to be energized when the receivers are energize. Also the transmitters are disposed at the central hub so as not to unbalance the wheel and sense each tire on a wheel, even when its a dual wheel at each location; and wherein a pair of receivers are disposed one at the back of a towing portion of an eighteen wheel truck and one at the back of a towed portion of an eighteen wheel truck so as to be responsive to the transmitters at each of the dual wheel monitors.
