SAN ANTONIO, Texas – Meritor and Pressure Systems International (P.S.I.) celebrated a milestone earlier this week when the one-millionth Meritor Tire Inflation System (MTIS) by P.S.I . rolled off the assembly line.

The companies said that as part of the celebration, 31 different trailers from Meritor’s fleet customers will be equipped with a part from the one-millionth MTIS by P.S.I. The finished milestone unit was unpackaged and disassembled into different components, which were incorporated into 31 units coming off the line and will be installed by seven key OEM manufacturers.

“In 1993, it would have been impossible to measure the impact an automatic tire inflation system would have on the trucking industry. The fact that now over one million systems have been produced is a true testament to the safety and environmental impact automatic tire inflation systems are having on transportation,” said American Trucking Association president and CEO Bill Graves, keynote speaker at the celebration.

Brett Penzkofer, vice-president and general manager, Trailer, added: “More than thirty trailers will travel the continent equipped with the MTIS by P.S.I. system containing a part from the one-millionth system. MTIS by P.S.I. is the preferred automatic tire inflation system among fleets due to its durability, reliability and overall simplicity. It’s an exceptional product that has been bringing great value to them for the last 23 years.”

MTIS is manufacturer for Meritor by P.S.I. in San Antonio and the product eliminates concerns about tire pressure loss by automatically maintaining proper and even pressure at all times, the companies claims. It can be installed on all major trailer axle models in North America.

“Manufacturing 1 million units is a milestone that far exceeds our competitors and speaks to our market leadership for a product with a growing customer base,” said Tim Musgrave, president and CEO for P.S.I.
