The TireMinder TM-88C 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-88C features a large display, an extra strength signal booster and 4 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).
