A wireless dual tire pressure monitor and equalizer apparatus is adapted to install on a vehicle dual wheel and connect to the two tire valve stems. The apparatus includes capabilities of monitoring individual tire pressure and transmitting tire data to be received by a remote receiver, equalizing pressure in the two tires when pressure is above a selected level, isolating the two tires when pressure is below the selected level, and transmitting warning signals upon detection of low pressure and air leaks. The apparatus further includes capability to integrate with available tire inflation systems for providing tire pressure monitoring and equalizing functionalities.
