Stay on top of tire pressure and temperature without constant manual checks. Pick cap sensors for fast setup, or go with internal options for added security and sealed batteries that can last at least 5 years. All systems use a signal booster—if your trailer has no battery, mount the booster on the tow vehicle or in the engine bay for solid reception.
Installation is quick—install batteries, thread sensors onto metal valve stems, and program the monitor. If you see a leak on an inner dual, check valve stem extenders before blaming the sensor. During long-term parking, removing sensors can help save battery life. For theft deterrence, decide if you prefer a lock nut or a set screw style.
Yes, if your monitor is compatible with internal sensors you can swap from cap to in-tire sensors. Confirm your monitor supports both sensor types before buying. Internal sensors help prevent a sensor going missing and keep wheels looking clean. Look for internal sensors with batteries that last at least 5 years.
Yes, some systems offer a mobile app that displays pressures and temperatures, even on Android Auto, so you don't need a separate dash monitor. You'll step through setup and calibrate to your tire pressures. High-pressure or slow-leak alerts help you react quickly on the road.
Yes, use the booster to ensure proper operation and range. If your trailer has no battery, mount the booster on the truck—ideally in the bed or under the frame for a clear path to the sensors. On smaller RVs, mounting in the engine bay works well and keeps it protected. Verify power, and plan for limited cable length when choosing a location.
Match the wheel's valve hole size—typically 0.453" or 0.625"—and use metal, bolt-in stems rated for your cold PSI. If integrating with a truck's factory system, confirm the sensor frequency and pressure limits; some factory sensors are limited to 110 PSI and smaller valve holes. Verify stems can handle 125-130 PSI if that's your requirement.
