A system for remote monitoring of vehicle tire pressure includes monitors mounted in the tires, each including a tire pressure sensor, a transmitter for transmitting a tire pressure signal, a battery for the transmitter, and a receiver for receiving an initiation signal. Initiators are mounted on-board the vehicle, each initiator associated with one of the tire monitors. Each initiator is for use in generating a low frequency initiation signal for receipt by a tire receiver to cause the transmitter to transmit a tire pressure signal. A vehicle mounted controller activates the initiators in order to generate the low frequency initiation signals, and processes the tire pressure signals to convey tire pressure information to a user. The controller further activates the initiators in order to generate a low frequency electromagnetic field for use in recharging the batteries in the tire monitors.
