TST 507 Tire Pressure Monitoring System for RVs and Towing

Do you tow an RV, boat trailer, cargo trailer, toad vehicle from your motorhome or haul commercially? If you do, you’d know that your biggest concern is tire blowouts. But by having the TST 507 tire pressure monitoring system though, you’ll receive an alert of tire pressure or temperature discrepancies instantaneously to help prevent those tire blowouts which could result in an accident or expensive inconvenience.

So, you can see why it’s so important to get the tire pressure monitoring system that fits all RVs, toads and tow vehicles. Because it’s not a matter of if your RV, tow vehicle or toad has a tire blowout but when.

This is precisely why it’s imperative to have a reliable tire pressure monitoring system that will signal tire pressure discrepancies before they happen.

The great thing about this tire pressure monitoring system is they aren’t just for RVs! A TPMS is also perfect for vehicles towing boat trailers or cargo trailers and even commercial trucks (18 wheelers, cargo carriers and box trucks).

So, after we’ve drove thousands of miles with our Truck Systems Technologies’ TST 507 tire pressure monitoring system, we’ll share important points on installation, how it works and our review.

Tire Safety - Tire Blowout

What causes tire blowouts?

“A tire blowout is a sudden rupture or malfunction of a part or an apparatus due to pressure, in particular the bursting of a motor vehicle or RV tire”. 

There are two causes of tire blowouts; temperature and pressure changes. If you don’t keep up with your tire maintenance and pay attention to the condition of your tires, chances of getting a tire blowout increase greatly.

Adding to that, exceeding your RV’s Gross Vehicle Weight Ratingalso known as GVWR, excessive speed and road conditions all play a huge part in how your tires will fair on the road.

Experiencing a tire blowout can be unnerving and place you and your RV into a dangerous situation broken down on the side of the road.

And if you’ve never experienced a tire blowout, know that they can be violent and cause your RV to handle much differently.

If you don’t know how to handle your RV or vehicle during a tire blow out, you and your RV has the potential of a catastrophic ending. 

However, if you’re prepared with the right tire safety gear that will actually alert you to tire issues BEFORE a blowout or flat, why on earth would you put off getting it?

So, let’s jump right into the information about the TST 507 Tire Pressure Monitoring System, its installation and our review.

We previously had a different manufacturer RV tire pressure and temperature monitor system installed on our Ram 3500. However, we weren’t overly excited about the competitor’s run-of-the-mill features.

So, we jumped on the opportunity to see what the TST 507 TPMS would do and see what the differences in operation are.

About the TST 507 Tire Pressure and Temperature Monitoring System

The TST 507  tire pressure and temperature monitoring system provides a real-time display of all tire temperatures and pressures on the color monitor. It provides both visible and audible alerts when a problem is detected with your tires before catastrophic failure.

This useful electronic tool can save you from a major accident or expensive RV repairs. Its external tire sensors are lightweight, water resistant and have an anti-theft device. This special security device ensures your sensors stay on your vehicles’ tires instead of mysteriously migrating to someone else’s.

Unboxing our TST 507 RV 6 C kit

Our TST 507 tire pressure and temperature monitoring system came with one color monitor display screen, six external theft-resistant cap sensors, power cords, and repeater antenna. In addition, a suction cup mounting system was included to adhere to the inside of our truck’s windshield.

Based on our RV set up, we did have to order four additional sensors to allow us to monitor our truck and 5th wheel tires.

The tire sensors come with pre-installed batteries and should be operational for well over a year. If the batteries need replacing, a low-battery alarm will sound to alert you.

You can purchase replacement batteries for your tire sensors. We always keep a few spares in case our sensors stops sending signals to our monitor.

Do note you’ll need specific batteries depending  on generation of TST 507 TPMS.

Also, depending on which generation of TST 507 tire pressure monitoring system you have, there’s also replacement O ring kits and applicable tools.

The TST 507 kit also came with an owners manual with simple installation and programming instructions.

Installation of the TST 507 Tire Pressure Monitoring System

STOP BEFORE PROCEEDING: Before starting the installation, consult with your particular tire manufacturer for tire pressure recommendations.

In the manual, there are a few installation methods. We chose to go with the best advised installation method by programming the sensors to the monitor and then installing them onto the valve stems.

Also, you can mount the sensors onto rubber valve stems so you won’t need expensive steel valve stems. Also, you can program the sensors for high and low pressure alarms depending on the type and size of your RV’s tires.

The TST 507 TPMS monitor is powered by the 12 volt system from your RV or from your tow vehicle or toad.

In our case, we plug our TST 507 into a cigarette lighter receptacle or use the USB cord to run it off a USB outlet. It just seems a lot easier and allows for getting the system up and running quicker.

Setting the Tire Temperatures and Tire Pressures

Set the high and low pressure alarms according to the tire pressure data decal on the inside of your vehicle’s door.

Most RVers use about a 10% high and 10% low parameter based on these settings.

After setting the pressure alarms, you’ll set the tire temperature alarm. The factory preset temperature doesn’t normally need to be adjusted.

Make sure you place a sticker number on each tire sensor when you program it so you can mount the proper sensor on the proper tire.

Always On Liberty - TST 507 TPMS Valve Caps

Mounting the sensors is as easy as unscrewing your old tire valve stem caps. Then, replacing them with the new anti-theft device and temperature sensors.

The monitor will begin to cycle through its display; showing the position and data for each tire almost immediately.

If you have an RV over 38 feet, you may have to install the supplied repeater antenna.

All you need is a 12 volt power source from somewhere in your coach. The repeater antenna will act as a midway signal point between the tire sensors and the monitoring system mounted on your dash or windshield.

Need more tire sensors?

You can easily add more sensors to your 507 system or replace an old worn out sensor. These sensors have a user replaceable battery and an anti-theft feature and work with the 507 TST system.

You can easily add flow thru sensors to your TST 507 system with this convenient 2-pack. The flow thru sensors allow you to air up your tires without taking the sensor off the valve stem. Flow thru sensors should only be used with metal valve stems.

When you change the batteries in your Flow Thru sensors you will need an O Ring replacement kit to replace the O-rings, screws, and valve stem gaskets if needed.

This kit also includes a small screwdriver that needed to remove and/or replace the batteries.

Now, if you don’t want to be bothered with changing out the batteries in your TST 507 sensors, there are Hybrid Sensors.

However, be aware they have a 3-4 year battery inside a sealed sensor. The whole sensor(s) must be replaced when the battery expires.

And lastly, if you’d rather not deal with external tire sensors completely, Truck System Technologies now offers a TST Internal System with 4 Sensors and COLOR Display with 3 year warranty.

For additional tires, you can add the appropriate number of  proprietary TST 507 internal sensors. They are laser-sealed and water-resistant. The Internal Sensors are mounted onto the wheel, so the tires must be removed from your RV for installation.

Also, the internal sensors do not have user-replaceable batteries. Again though, once the batteries are depleted, you need to replace them with new sensors. 

Our review of the TST 507 Tire Pressure Monitoring System:

We’ve found the accuracy and dependability of the TST 507 Tire Pressure Monitoring System knocks it out of the park. The installation of the tire sensors and programming is easy and doesn’t take long. The full-color monitor display is super easy to read and extremely accurate.

Above all, the TST 507 TPMS constantly monitors our RV and truck’s tire pressures and temperature better than our former TPMS system.

In our opinion, the TST 507 RV tire monitoring system is a vital piece of electronic equipment that every RV owner should have.

Having this peace of mind will help keep your family and RV safe by displaying the current pressure and temperature status of your RV and tow vehicle or toad tires.

Is the TST 507 transferrable to other RVs or tow vehicles and trailers?

Yes, the entire system is easily transferable to your next RV so consider it as an investment!  

In June 2019, we traded in our fifth wheel for our Winnebago View Class C motorhome. We removed the entire TST 507 tire pressure monitoring system from our fifth wheel to transfer to our View.

With simple reprogramming, we now have complete confidence while driving and pulling our Jeep toad vehicle.

Our review of the TST 507

We can give full testament that the TST 507 Tire Pressure Monitoring System saved us and our motorhome from a catastrophic accident. One of our inner dual tires on our motorhome kept giving us a low pressure reading.

After evaluating and replacing the battery on that particular tire sensor, we received the same low pressure reading.

So, we took our motorhome to a professional truck tire center to have the tire pulled and evaluated. The technician found that our tire had been patched and was coming apart inside the tire. 

Had we not had the alerts from our TST 507, we would have incurred not only damage to that tire and the paired dual tire next to it.

But also, our motorhome underbelly components which would have totaled thousands of dollars from damage.

Wrapping up

Now that we’ve had our TST 507 tire pressure monitoring system on our truck and fifth wheel, and now our Winnebago View Class C motorhome (and Jeep), we are confident to recommend this particular tire safety component. 

The TST 507 RV tire pressure monitoring system is an invaluable tool that will help keep you and your family safe on the road for years to come.
