This paper describes the monitoring and managing of tire pressure. The cheap micro controller working in conjunction with existing wireless transmitters and tire pressure monitoring devices for motor vehicle applications is designed. The main goal is to develop a working unit capable of detecting pressure in multiple tires and adjustment of pressure in the tires to the appropriate predefined values. The controller that interfaces with the tire receiver to correctly capture and manipulate the data and the pressure management capability is also discussed. The "transportation recall enhancement, accountability and documentation" (TREAD) act requires automakers to gradually provide tire pressure monitoring solutions for all motor vehicles. This system is mainly designed and implemented for the use on truck trailers.
