Rence Oliphant said Hendrickson's TIREMAXX PRO system automatically inflates and deflates tires to keep air pressure steady and balanced at every wheel position.
Based on its current inflation-only system, Tiremaxx Pro continuously monitors pressure in each tire to prevent overinflation when temperatures increase and to add air when pressures fall below set levels.
Maintaining tire pressures within a narrow optimal band and ensuring that every tire on a trailer is balanced will help fleets get maximum tread life, according to Hendrickson. The system's patented technology features a mechanical design without electronics or pressure switches, and a rotary air connection integrated into the axle hubcap. It will be available in early 2011.
