More than 80% of fleet tire problems are caused by
improper inflation. In fact, tires represent the second largest financial
expenditure for most fleets. The Meritor® Tire Inflation System (MTIS) by P.S.I.
is an automatic tire inflation system (ATIS) that keeps tires properly inflated.
Unlike equalization systems that merely distribute air from one tire to another,
MTIS uses compressed air from the trailer air system to inflate any tire that
falls below a pre-set pressure when the trailer is moving. The system increases
tire life, fuel efficiency and safety.
This innovative system connects all tires on the trailer to a controlled air
supply to fill and maintain air pressure at a constant and proper level --
even while the vehicle is moving. As air pressure decreases from the tire
manufacturer's recommended level, MTIS automatically routes air supply to a
control box and then into the axle. The air is then distributed to each tire
helping extend tire life and allowing for more even wear and maximized recap
Self-contained on the trailer, MTIS can easily adapt to any tractor. The
system can be installed on any type of trailer - from dry vans and liquid
tanks to flat beds, and intermodal trailers and chassis.
Meritor Tire Inflation System (MTIS) by P.S.I. is the market leader for
safety, fuel economy, longer tire life, reduced maintenance, increased
uptime and faster payback. It often pays for itself in six months. A
warning light alerts the driver immediately when tire inflation occurs and
doesn’t require vehicle electrical power.
