Pressure Systems International

The company that started an industry - literally.

About P.S.I.

Since 1993, P.S.I. has equipped over 1.8 million trailers with our patented Automatic Tire Inflation System.

Nearly 30 years ago, P.S.I. started with a truly innovative concept of automatic tire inflation. During that time, we commercialized a concept that was initially referred to as a gimmick.

Over time, customers began to recognize the value it delivered and its low coast of ownership. We had started a new global industry, and in North America it is specified on approximately 70% of all new trailers.
