TST 507 Flow Through TPMS RV Tire Pressure Monitoring System Review

TST 507 Tire Pressure Monitor Review

For safety, we wanted a TPMS on our travel trailer. We selected the TST 507 Tire Pressure Monitor. Check out our review of the TST 507 Flow Thru System.

Why Buy an RV Tire Pressure Monitoring System

An RV Tire Pressure Monitoring System (TPMS) can be a useful safety improvement. When you are travelling down the road at 60 miles per hour, an issue with your tires could have a bad outcome. While we have been pretty lucky in our travels, we have heard stories of tires coming apart and hitting an RV or camper. It can cause serious damage. A sudden loss of tire pressure could cause you to lose control of the vehicle. With that in mind, we decided to add a TPMS to our Grand Design Transcend this year.

A TPMS enables you to monitor the pressure and temperature of your tires. If it detects that something is going wrong, it will alert you. While they aren’t perfect, tire pressure monitors can reduce the chance of a serious tire-related issue.

How Does a TPMS Work

Most tire pressure monitoring systems consist of sensors on the tires and a monitoring unit kept near the driver. The sensors can be mounted inside the tire or added to the valve stems. Many RVers use systems which have valve stem sensors. To ensure the sensor signal reaches the monitor, a sensor signal repeater is often installed somewhere between the sensors and monitor.

Why Did We Buy the TST 507

Several manufacturers make good tire pressure monitoring systems. In addition to the TST, we considered systems from TireMinder and Lippert. They all had good features and positive reviews. In the end, we selected the TST 507 TPMS (TST-507-04-FT).

There were three main features we liked about the TST. Probably the most important differentiator for us was the flow thru sensors. On some models, you’ll have to remove the sensors in order to add air to your tires. With the TST flow thru sensors, you can add air to the tire without removing the sensors.

Be aware that the flow thru sensors are relatively heavy. They should be installed on tires with metal valve stems. We had recently upgraded our tires and had metal valve stems installed. If you have rubber valve stems, you may want to consider a different model with lighter sensors.

The second feature we liked was that the small antenna on the monitor. On some units, you’ll have to extend the antenna like on an old radio. Thinking of how that would fit in the cab of our truck, an extending antenna didn’t seem like a good fit.

Finally, it was nice that the TST monitor stays on, cycling through each tire every few seconds. On some brands, the monitor display will shut off. It’s nice to be able to keep an eye on the tire pressure as we go.

One other thing to note is that the TST 507 can be used with multiple trailers. While we mainly tow our camper, it is good to know that we have the flexibility to use this system with other towables such as a boat or another RV.

We read and watched a lot of reviews prior to making our purchase. Among the most helpful reviews were those by TechnoRV. You may want to check out the information and videos about the TST 507 on the TechnoRV site. <affiliate link>

How to Install the TST 507 TPMS

The TST 507 is relatively easy to install. Here are the basic steps.

  • Remove the components from the package
  • On the monitor, set the tire positions and then set the pressure and temperature ranges
  • Pair the sensors to the monitoring unit
  • Install sensors on your tires
  • Install the repeater by connecting it to the battery then mounting the sensor repeater using the provided Velcro tape.

How Well Does the TST 507 Work

We’ve had the chance to use the TST TPMS on several trips. So far, it works great. The monitor display is clear, although it can be a bit hard to read if I am wearing sunglasses on a bright day. The battery on the monitor seems to last a long time. It can be easily charged using a USB connection, with or without the cigarette lighter adapter.

About the only improvement we would like to see is a way to turn off the power for the sensor repeater when we aren’t travelling. It would be great if it had an on/off switch. Or, even better, if it could be installed in such a way that using the RVs power shut-off would also turn off power to the sensor repeater.
