More than 80 percent of fleet tire problems are caused by improper inflation. In
fact, tires represent the second largest financial expenditure for most fleets.
The award-winning Meritor Tire Inflation System (MTIS™) by P.S.I. 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.
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.
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. 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. Use our payback

The MTIS ThermALERT™ option adds high-temperature protection to the
industry-leading automatic tire inflation system. ThermALERT wheel-end
heat-sensing technology alerts drivers to take preventive action that avoids
damage caused by elevated wheel-end temperatures. ThermALERT reduces
vehicle downtime, risk and costs to keep your business moving ahead. A patented
eutectic insert (thermal screw) in a ThermALERT-equipped spindle plug melts 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. In
addition, when the driver exits the cab to inspect, an audible signal will be
heard at the suspected wheel end. The alert can also be communicated to the cab
through the Meritor WABCO PLC Display or to an operations center via a telematic
system.
