A low tire pressure warning system includes a tire pressure sensor constructed to be mounted within each of the tires on the wheels of a vehicle. Each tire pressure sensor includes a pressure switch coupled to a transmitter and a battery, with the pressure switch being constructed to connect the battery to the transmitter so as to activate the transmitter when pressure within the tire drops below a low value. A receiver is constructed to be mounted within the vehicle in communication with the transmitters and a low tire pressure warning indicator is coupled to the receiver so as to be activated when the receiver receives a signal from any one of the transmitters.
