A free video CD from Hendrickson Trailer Suspension Systems highlights the Tiremaax automatic tire inflation system. This CD, Tiremaax Tire Inflation System (L882), describes this option for Intraax and Vantraax trailer suspension systems. Tiremaax provides a responsive tire inflation system that taps the trailer air supply to maintain tire inflation.

Governed by an electronic control unit (ECU), the system detects low tire pressure and signals the operator to situations or circumstances requiring attention. It responds by directing air from the trailer tank to one or more tires when the inflation pressure dips below the pre-set level.

With Tiremaax, air travels from the supply tank through air lines inside the axle to the wheel ends. A bolt-in, ball-bearing rotary union allows air to flow through the axle spindle to the rotating hubcap fitting, and hoses connect the hubcap tee to the tires.

A trailer-mounted indicator, designed to be installed in view of the driver, notifies the operator to system status and maintenance requirements. Check valves help prevent tire pressure loss back through the system. Manual fill and pressure checks may be accomplished at the hose ends.

Tiremaax activates only when needed; constant air pressurization to the tires is not required. For a free video CD, phone Hendrickson International, Trailer Suspension Systems, Canton OH, toll free at 866-743-3247.
