TST TST-507-RV-4-C Cap Sensor Tire Pressure Monitoring System - Color - 4 Pack

Easy to install. Easy to program. Sensors show 2 pounds less than what I get with my air gage. I am using these sensors on a 35 foot travel trailer. I did need to use the booster that came with the sensors. Without the booster, sensors would drop. Have had no issues when using the booster. Used product on a recent 1400 mile trip. No issues with sensors or monitor. On several occasions prior to having the sensors, I have driven through debris and trash on the highway. Always concerned that trailer tires could get punctured and I would not know it. With the low PSI warning and the air leak warning, I feel better knowing the tires are monitored.

I bought the system prior to our first long trip. It started alarming about mile after we left our campsite we able to get our tire repaired before any damage was done to us or the RV.

There is no other good way to monitor your trailer tires without a system like this. Given the importance of pressure to tire longevity and safety, having a remote monitor that you can trust should be high on your list of RV add-on's.

Quick and easy installation. Only minor issue is monitor only updates every 5 minutes. Monitor will display immediate tire inflation or temperature alert. This is a plus for this tire monitoring system.

Works very good. But we have been worked to remove quickly after stop. Because they are easily stolen.

I feel confident now pulling my trailer down the road knowing if I start losing air in a back tire I’ll have some time to pull over before catastrophic failure.

Works well
