Abstract
The diaphragm of a dual tire equalizer has an axial probe actuating or not actuating a switch in a radio frequency transmitter circuit mounted on the wheel. The transmitter sends a signal varying, depending on the condition of the switch. A radio frequency receiver on the vehicle and connected to an indicator in the driver's cab responds to the signal and issues appropriate information to the driver concerning condition of the equalizer.
