Minder Research's TireMinder Wireless Tire Pressure Monitoring Systems (TPMS) are designed to continuously monitor tire pressure and temperature, and offer both visual and audible blow-out warnings. Transmitters screw onto the tires' valve stems and send readings to the easy-to-read digital monitor inside the car, RV or truck. The user-programmable system signals and sounds alarms for tire pressure loss or if tire temperature exceeds 167°F/75°C.
