TST SmartTire turns your phone and CarPlay into a real-time tire health dashboard for trucks, trailers, motorhomes, and fifth wheels. Pair the SmartTire Hub once, sync each sensor to its tire, and watch live pressure, temperature, and sensor battery for every wheel — including duallies and the spare.
