The TireMinder TM-77 RV Tire Monitoring System makes it easy to stay informed of any tire pressure or temperature issues you may have on your RV, motorhome, 5th wheel, or trailer. The TireMinder TM-77 features a large display, an extra strength signal booster and 6 standard transmitters.

The large, crystal clear, 3.25″ display provides simultaneous pressure and temperature readings and allows you to automatically scroll through each tire position with the push of a button. An upgraded high-power antenna and Rhino signal booster deliver maximum signal strength. The Multi-Vehicle Disconnect (MVD) allows for up to 3 separate vehicles to be added and exchanged in just a few clicks.

Transmitters on the valve stems check for tire issues every 6 seconds. If no issue is found, transmitters send updated pressure and temperature readings every four minutes. Display provides both visual and audible alarms, including blowout alarm, high-temperature alert (at 167°F), low and high-pressure alerts (15% below and 20% above baseline), and fast and slow leak alerts (3 psi or more in 2 minutes or less and 6 psi or more in 10 minutes or less).
