Pressure Systems International Inc. (PSI) reported that fiscal year 2005 sales of the Meritor Tire Inflation System (MTIS) by PSI increased 30 percent over 2004.

MTIS is the most accepted tire inflation system in the heavy duty trucking industry with one in every 10 trailers built in North America equipped with the system, according to Frank Sonzala, executive vice president for PSI, and Barry Eckel, director of sales and marketing ArvinMeritor for MTIS. As a result of its record 2005 sales, MTIS now protects nearly 2 million tires every day against under-inflation.
Pressure Systems International was the first to develop automatic tire inflation for heavy vehicles in the early 1990’s. PSI's pioneering efforts in the field have yielded a number of patented technologies, such as the press plug and thru-t (developed jointly with STEMCO), which allow the use of the axle tube as the conduit for air pressure, greatly improving reliability. PSI's work in sealing rotary surfaces has enabled the company to offer a truly automatic system with constant air pressure available for rapid tire inflation when needed.
In early 2004, PSI put its Technology Tractor and Trailer into service through its Research & Development Department. This vehicle is outfitted with wheel-end computer data recorders that provide a true picture of the dynamics of tire inflation in actual road travel conditions. The data gives PSI important information on the affects of altitude, climate, weight, speed and temperature on tire and wheel-end components related to automatic tire inflation. The newest innovation to the Meritor Tire Inflation System by PSI features automatic tire inflation with a wheel-end high-temperature warning alert. The enhanced system was developed because fleet customers have been requesting the ability to detect potential wheel-end failures before they become critical.
