The Meritor Tire Inflation System (MTIS™) is an automatic tire inflation system that keeps tires properly inflated. The system increases tire life, fuel economy and safety by helping to compensate for pressure losses resulting from typical tire punctures and other slow leaks. This innovative system connects all tires on the trailer to a controlled air supply to fill and maintain tires at the desired pressure setting, even while the vehicle is moving.
Unlike equalization systems that merely distribute air from one tire to another, or monitoring systems that simply tell when a tire has lost air pressure, MTIS™ uses compressed air from the trailer’s air system to inflate any tire that falls below a preset pressure whenever the vehicle is in operation. As air pressure drops below the tire manufacturer’s recommended level, MTIS™ automatically routes air through a control box and through the trailer axles to refill any underinflated tires. By maintaining proper pressure, MTIS™ helps extend tire life and allows for more even tread wear and maximized recap potential.
Self-contained on the trailer, MTIS™ can easily adapt to any tractor. The system can be installed on any type of trailer, from vans and tanks to flatbeds and container chassis. MTIS™ kits are also available for retrofit.
The MTIS ThermALERT™option adds high-temperature protection to the automatic tire inflation system. It uses wheel-end heat sensing technology which alerts drivers to take preventive action and avoid damage caused by elevated wheel-end temperatures – reducing vehicle downtime, risk and costs. If the wheel end reaches abnormally high temperatures, it allows air to escape through the hubcap tee vent and triggers the system’s exterior light. The alert can also be communicated to the cab through the Meritor WABCO PLC Display or to an operations center via a telematic system.
