The goals of this project include gaining a better understanding of the effectiveness of tire pressure monitoring systems when used in the real world, thoroughly documenting the cost/benefits, and encouraging the development and deployment of these systems by convincing carriers that they have the potential to enhance the safety of their fleets, streamline operations, and have a reasonable payback period. This project will: (1) update and expand upon FMCSA past market research study of tire inflation maintenance and management products, (2) design and conduct an FOT of these technologies, and (3) conduct a symposium and public meeting on tires for heavy highway vehicles.
