ABSTRACT:
A tire equalizer comprises a housing having upper and lower chambers divided by a flexible diaphragm opposing a seat in the upper chamber connected to one of the tires. The diaphragm is urged toward the seat by a spring-pressed inverted cup larger in diameter than the diaphragm and having an arm extended longitudinally from the cup away from the spring. The arm is curved in horizontal cross-section and its upper end is formed with a slot receiving an off-center pin on the back of an indicator disc. Also connected to the upper chamber is a fill conduit, and a conduit to the other tire.
