The document summarizes a Tyre Pressure Monitoring and Inflation System called the TPH hub. The TPH hub is a device that fits onto truck and trailer wheels to monitor and manage tyre pressure. It consists of a hub with two air gauges and air lines connected to the tyre valves to make inflating easy. The TPH system aims to improve safety, reduce costs from fuel and tyres, and lower greenhouse emissions by enabling accurate and constant monitoring of tyre pressure.
