Product Review: TST 507-RV-6-C Tire Monitoring System

By:  Lisa & Dan Brown

1st May, 19

Recently, we collaborated with TechnoRV on a project to install and evaluate the Truck System Technologies (TST) 507-RV-6-C tire pressure and temperature monitoring system. We already had a different TST brand installed in our Landmark 365 that we weren't quite happy with, so we jumped at the opportunity to try out a new system.

Let’s Talk About the TST 507-RV-6-C

The Truck System Technologies (TST) 507-RV-6-C is the newest tire pressure and temperature monitoring system on the market. It claims reliability, ease of installation and use. The cost is also comparable to others on the market.

The TST provides a real-time display of all tire temperatures and pressures on the color monitor. The monitor provides both visible and audible alerts if a problem is detected with your tires, and the system will alert the driver when there is a change with one or more of the tires before it gets to the point of catastrophic failure - saving you from a major accident or expensive RV repair(s).

The TST external tire sensors have an anti-theft cap to ensure your sensors stay on your RV’s tires and don’t migrate to someone else's. The sensors can also be mounted on rubber valve stems, so no expensive steel valve stems are needed.

What’s Included in the TST-507-RV-6-C Kit

Here is what the system includes:

  • Real-time display of tire pressure and temperatures
  • External sensors for easy installation
  • Light, compact and water-resistant sensors
  • Accurate pressure readings
  • Pressure range of one to 218 pounds
  • One-year sensor battery life
  • User adjusted high-low pressure alarm levels
  • Display can monitor up to 38 tires (0-218 PSI)

Our TST-507-RV-6-C tire pressure and temperature monitoring system comes equipped with an information and installation manual, a single-color monitor display screen, six external theft resistant cap sensors, all the necessary power cords and a repeater antenna. It also includes a suction cup mounting system that we chose to mount on our driver's side windshield.

We had a total of ten tires to be monitored, so we did have to acquire four more sensors; six on our truck and four on our Landmark 365 fifth-wheel.

The sensors come with pre-installed CR1632 batteries that should be operational for well over one year. You will get a low battery alarm when any of the sensors need replaced. You can purchase the CR1632 replacement batteries at most stores or Amazon.

Before beginning the installation process, we recommend reading over the manual in order to have a clear understanding of what you’ll need, how much time it could take you to install, etc. The TST-507-RV-6-C manual is pretty straight forward and gives great guidance on how-to program the tire sensors.

Additionally, we recommend confirming what the tire pressure should be with your tire manufacturer and set the high-and-low pressure alarms accordingly.


We began by mounting and energizing the color monitor, followed by programming each sensor off the wheel. The monitor is powered by the 12-volt system of your RV or your tow vehicle, so it doesn't use much power in order to operate.

You can plug the monitor into a cigarette lighter receptacle or use the USB supplied power cord to run it off an USB outlet. For us, using the USB outlet seemed a lot easier and allowed for quicker power-up.

Again, it bears repeating; check with your tire manufacturer(s) to see what your tire pressure should be - then set the high-and-low pressure alarms accordingly. Most RV owners use about a 10% high and 10% low parameter for these settings. Once your tire pressures have been set, you’ll set the tire temperature alarm.

We placed the number sticker from the sheet (also included in the kit) on each tire sensor – that way, when we programed it, the proper sensor was mounted on its designated wheel. Mounting the sensors is as easy as unscrewing your old tire valve stem caps and replacing them with the new sensors. Once the sensors were all in place, the monitor began to cycle through its display -showing the position and data for each tire almost immediately.

*Important to note – big-rig fifth-wheels or travel trailers over 38 feet may require the supplied repeater antenna to be installed.

In order to install the repeater antenna, you’ll need a 12-volt power source from somewhere in your RV. For example, our repeater antenna is mounted in the kitchen pantry of our 41+ foot Landmark Ashland model. The repeater antenna acts as a midway signal point between the tire sensors and the monitoring system mounted in the cockpit of our truck.

Our Thoughts on TST-507-RV-6-C Tire Monitoring System

In our opinion as veteran RVers, this system is a vital piece of safety equipment that every RV owner should be using. Oh, and if you're ever thinking of trading in your current Heartland unit for another, the entire system is easily transferable. In order to transfer from one RV to the another, you’ll dismount all the sensors and the monitor and mount the tire sensors and reprogram them for your new one.

The accuracy and dependability of the TST-507-RV-6-C definitely won us over compared to our previous tire monitor system. The color monitor display is easy to read and extremely accurate. Its ability to constantly monitor our tire pressures and temperature puts our minds at ease. Most of all, the installation and programming process was quick and easy.
