ABSTRACT:
This invention is a method and system for reporting the under or over pressure conditions on motor vehicle tires. The device is comprised of air hoses, pressure sensors, radio transmitters with antennas, a radio receiver, a display unit with lights, batteries, lights, and associated electrical components. An assembly mounted on the front of each wheel, over or in place of the hubcap, consists of an air pressure monitor utilizing air pressure inflation valves, a radio transmitter with battery cell, a radio transmitter antenna, and high/low indicator lights. Air hoses attached to each tire's valve stem are connected to the air pressure inflation valves of the air pressure monitors. The wheel mounted transmitters are powered by a low voltage battery that is normally powered off until activated by the changes of the pre-set air pressure of the tire air pressure monitoring sensor.
