Meritor Tire Inflation System by PSI enhances fuel economy, according to study

Meritor Inc and Pressure Systems International (PSI) announced the results of a study showing a 1.4% improvement in fuel economy using the Meritor Tire Inflation System (MTIS) by PSI.

The study was conducted by the Federal Motor Carrier Safety Administration's Office of Analysis, Research, and Technology. Using two fleets, Gordon Food Service of Grand Rapids MI and Sheetz Inc of Altoona PA, the agency tested the effects, costs and benefits, or influence on maintenance intervals as well as their impact on safety and performance of tire inflation systems and tire pressure monitoring systems.

In addition to better fuel economy, the fleets saw an increase in tire life, experienced fewer road calls and correct tire pressures were consistently displayed.

MTIS by PSI keeps tires properly inflated. This improves tire maintenance management, increases trailer uptime and return on investment. It can be installed on any type of trailer.

The system adds life to tires, increases fuel efficiency, improves safety, maximizes recap potential, and keeps trailers on the road. It is an automatic system with constant air pressure available when needed. The patented rotary union is the only moving part in the system, and the patented ThermALERT option notifies drivers of excessive wheel end heat. MTIS with ThermALERT accounts for more than half of PSI's production. Visit or for more information.
