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

Recently, we partnered with TechnoRV to evaluate the Truck System Technologies (TST) 507-RV-6-C tire pressure and temperature monitoring system. We already had a different brand that we weren't quite happy with, so we jumped at the opportunity.

Let’s Talk About the TST 507-RV-6-C

The TST 507-RV-6-C is the newest tire pressure and temperature monitoring system on the market. It's reliable, easy to install and easy to use. It's also comparable in cost to other models on the market.

The device shows all your tire temperatures and pressures on a color monitor. If one of your tires has a problem, the system sounds an alarm. It provides audible and visible alerts to the driver, helping save you from a major accident or expensive RV repair.

The TST's external tire sensors have an anti-theft cap to ensure your sensors stay on your RV tires. Plus, you can also mount the sensors on rubber valve stems, which means you don't need to install expensive steel valve stems to use this product.

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

The system includes:
  • Real-time displays of tire pressure and temperatures
  • External sensors for easy installation
  • Light, compact and water-resistant sensors
  • Accurate pressure readings
  • Pressure range of 1-218 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. And it also includes a suction cup mounting system that we chose to mount on our driver's side windshield.

Because we had a total of ten tires to be monitored, we did have to buy 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 operate the sensors for well over one year. You will get a low battery alarm when any of the sensors need replacing. You can purchase replacement batteries at most stores or Amazon.


Before beginning the installation process, we recommend reading over the manual to have a clear understanding of what you’ll need and how much time it will take. The manual is pretty straight forward and gives great guidance on how to program the tire sensors.

And we recommend checking what the tire pressure should be with your tire manufacturer to set the high and low pressure alarms.

First, we began by mounting and powering up the color monitor. Then, we programmed each sensor off the wheel. The monitor uses the 12-volt system from your RV or tow vehicle, and it doesn't use much power to operate.

In other words, you can plug the monitor into a cigarette lighter fuse or use the USB supplied power cord. For us, using the USB outlet seemed a lot easier and allowed for a quicker power-up.

We'll say it again: check with your tire manufacturer to confirm what your tire pressure should be. Then set the high and low pressure alarms accordingly. Most RV owners use a 10% high and 10% low range for these settings. Once your tire pressures have been set, you’ll set the tire temperature alarm.

Next up, we placed the included number stickers on each tire sensor to make sure the proper sensor was mounted on each 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.

Repeater Antenna

Big-rig fifth-wheels or travel trailers over 38 feet may require installing a repeater antenna. However, it comes standard in the installation kit.

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

Our Thoughts on the Tire Monitoring System

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. And 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. So if you ever trade in your current RV for another, the entire system transfers easily to your new rig.

In conclusion, as veteran RVers, we think this system is a vital piece of safety equipment that every RV owner should use.
