RV Tire Pressure Monitor with 4 Wireless Sensors

The Tymate TM7 Tire Pressure Monitoring System keeps your tires safe and your devices charged. Simply plug it into your car's cigarette lighter for instant tire pressure and temperature monitoring with accuracy of ±1.5 PSI. The system alerts you with six different alarm modes for high pressure, low pressure, fast leaks, high temperature, low battery, and lost signals. See all information clearly on the color LCD screen with adjustable backlight that works in any light. The TM7 detects pressures from 0 to 144 PSI and works with cars, SUVs, trucks, RVs, and trailers. Two built-in USB ports let you charge phones and tablets while driving. Setup takes just five minutes with no wiring needed. Perfect for older vehicles without factory TPMS or anyone wanting extra tire safety. The system self-calibrates to your tire pressure and sends signals up to 100 feet away. Includes four sensors, CR1632 replacement batteries, and a user manual. Install with metal valve stems for best results.
