This TST tire pressure monitoring system monitors the pressure and temperature level of the tires on your RV, motorhome, 5th wheel, motor coach, or trailer. The system utilizes sensors that attach to the valve stems of your tires. When a tire sensor detects an anomaly, it will wirelessly transmit an alert to the included digital color monitor. Your monitor will emit flashing lights and an audible alert to notify you of an issue, and it will display details regarding the anomaly. A booster is included to strengthen and amplify the signal that the sensors are sending to the display monitor.

Initial Setup

The TST TPMS is easy to set up and includes all mounting hardware and tools for installation. First, assign the tire sensor positions through the monitor's Learning Mode. Label each sensor with the corresponding numbering code sticker so that you know which sensor is programmed to which tire position. When you are setting up the sensors make sure the one you are programming is at least 2' away from the other sensors. Otherwise the other sensors will interfere with the sensor you are attempting to program. Once the tire sensors have been recognized by the monitor, attach them to the valve stems of your vehicle's tires. Next, install the booster and connect it to a 12-volt power source on your vehicle or trailer.


Use the included suction cup holder to mount the color monitor on your windshield so you can monitor your tires while you drive. You can also use the included rubber, non-slip cradle mount to set the monitor on your dashboard.

TST Color Monitor Display

App Diagram

  1. Current Tire Selection - The tire icons indicate the position of your tires. A solid tire icon indicates that tire is programmed into your current setup. A blinking tire icon indicates that tire is experiencing an anomaly.
  2. Sensor Low Battery Alert - This displays when one of the sensor's batteries is low. The corresponding tire light will also flash to indicate which sensor's battery is affected.
  3. Display Battery Level Indicator - Shows the charged level of the internal battery. When this icon shows one bar it is recommended to charge the display as soon as possible. It takes approximately 4 hours for the battery to fully charge.
  4. Out Of Parameter Alert - This icon will flash during a high or low pressure alert, a high temperature alert, or a fast leak alert. In conjunction with this flashing light, the affected tire light will flash, the HI or LO PRESSURE, HI TEMP, or FAST LEAK indicators will light up, and an audible alert will sound.
  5. Display Alerts - These icons, along with the specific tire icon, will light up to indicate HI or LO PRESSURE, HI TEMP, or FAST LEAK. The bottom row indicates which programming mode you are in.
  6. Red LED Indicator - Lights up during an alert.
  7. Antenna - The multidirectional antenna helps eliminate electronic interference when paired with the signal booster.
  8. Temperature Indicator - Displays the current temperature of the selected tire in Fahrenheit or Celsius. This will also display your selected high temperature parameter during programming.
  9. Tire Pressure Indicator - Displays the current tire pressure of the selected tire. This will also display your selected high and low pressure parameters during programming.
  10. Power Switch - Lets you turn the monitor on and off.
  11. Charging Port - Plug the included USB cable into this port to charge the monitor. The side power switch will not turn off the display when constant power is applied to the unit.
  12. Backlight and Motion Detector - The backlight turns on when the vehicle is in motion, and there is little ambient light. It will sense periods of inaction and the display will "go to sleep" until the vehicle resumes motion.

TST Color Monitor Function Buttons

App Diagram

  1. GO Button - Press the GO button to tell the system where to "go". When pairing the sensors, once you have the tire icon flashing that you want to code, hit the GO button to tell it to get its unique code. If you only want to code a trailer, press the GO button to tell it to go to the trailer. When moving from axle to axle to set your warning pressures, hit the GO button to go to the next axle or next trailer.
  2. SET Button - Press the SET button to program your warning parameters, or to go into coding and set your configurations. This button locks in all specific settings.
  3. BACK Button - Press the BACK button to leave programming, or take the system back to the previous screen. If you need to remove a sensor code, use this button in the coding section to take the sensor position back to the factory settings.
  4. + Button - Press the + button to increase the temperature and pressure settings from the factory defaults. You can also scroll forward through your tires. Press the + button in conjunction with the GO button to drop your towing vehicle from a setting and add it back in.
  5. - Button - Press the - button to decrease the temperature and pressure settings from the factory defaults. You can also scroll backward through your tires. Press the - button in conjunction with the GO button to drop your towed vehicle from a setting and add it back in.

Multiple Wheel Layouts


You can program multiple layouts into the monitor, and you can scroll through each setup on the screen. This system can support up to 4 tire layouts and up to 38 tires total. Make sure to set your high and low pressure alarms for each layout that you are using. Some examples of popular layouts are shown above.

Tire Sensor Installation

Tire sensor Install Diagram

  1. Place the included wrench around the sensor. You must use the wrench to install or remove the sensor from your tire's valve stem.
  2. Screw the sensor onto the valve stem. Tighten the sensor until the air stops leaking and the sensor bottoms out on the valve stem. Give it a slight twist to fully seat the sensor while being careful not to over-tighten

Note: To inflate or deflate a tire you must remove the sensor.



The booster - or repeater - amplifies the signal strength that the sensors send to the monitor. Booster installation requires a 12-volt power source. It is waterproof and can be mounted inside or outside your vehicle with the included mounting hardware. On a trailer, you can mount it in the battery box in front of the propane bottles. On a 5th wheel, you can install it in the house battery bay underneath the overhang. You will want to place it below the bank of mirrors so they don't bounce the signal back and cause the system to malfunction. On coaches with towed vehicles, you can install it in the back battery bay. The power draw is so minimal that you can leave the booster installed without running the battery down. If you decide to unhook it for storage remember to reconnect when you are ready to hit the road. A red light on the repeater indicates that the unit is connected to power and operating correctly.

The TST 507 TPMS works flawlessly. In the year of ownership, it saved me from an expensive blowout. Unbeknownst to me, I picked up a very large 1/2"x 4" bolt in the passenger side rear tire of my 39' Montana trailer. The TST-507 system alerted me to the loss of air pressure in that specific tire, and I was able to avoid a complete blowout or worse the tire delaminating while at highway speeds. I would never consider towing a trailer without the TST system.

After 1 year, the TST system has been working perfectly and already saved us from a catastrophic tire failure.
Robert B - 05/31/2022


The TST TPMS tire sensors have worked extremely well on my RV trailer. I put 5000 miles on my trailer in 2020 and the tire monitors give me peace of mind as I travel down the highway.

The product continues to work great and give me piece of mind on our RV trips. As a precaution, I installed new batteries in the sensors for the 2022 RVing campaign.
Richard - 08/17/2022


As usual etrailer came through with EXCELLENT customer service. I ordered this TPMS system on Sunday Aug 29th after receiving a different TPMS system that was meant for metal valve stems, I have rubber valve stems. My mistake for ordering the wrong product. George C reviewed my order and helped push this order through in an expedited manner to get me the correct system 2 days later. Overall the instructions and ease of set up for this product is very good. I had to do some fine tuning after my initial set up and I will do some additional fine tuning to a couple of parameters before our next trip in a few weeks. We used this system on our Labor Day weekend trip and I was at ease the whole time, knowing that I should have advance warning of an impending tire failure with this system on our trailer. I mounted the repeater underneath the nose overhang behind the battery box mount and the suction cup to the lower left corner of the windshield, so as not to impair my field of vision out of the windshield. One thing I did add to this after we got back home was, I ordered from TST Truck Systems, and add on display visor that slips over the top and sides of the display to hopefully shade the display from some of the sunlight , making it a bit easier to see in the daylight.


The setup was straight forward and the display was easy to read at all times. It seemed to work fine without using the booster hauling a 38' gooseneck trailer. However after about 3 to 5 hours of traveling it would loose signal on one or two tires then the whole display would quit showing anything. Going back trough the manual it does mention that using without the booster may void the warranty. I have since installed the booster but have not had a trip longer than two hours to see if this fixes the issue.


We use these TST TPMS sensors and booster on our horse trailers, utility trailers, and live in trailers. They add a great degree of safety and if you have ever towed trailers and have had good tires fail due to low pressure and/or heat, you don't want to leave home without them. I am an ASE certified mechanic and my wife raises horses. We put many miles on our trailers and although I do all my own tire replacements, nails and other road debris find a way to puncture otherwise healthy tires. The problem with a trailer unlike your tow vehicle which has TPMS installed, is that trailers aren't required to have TPMS as yet. One doesn't know there is a problem until a tire has failed sometimes taking the tandem tire with it. Why would you not want to protect these wonderful animals and the traveling public at large by knowing what condition your tires are in on the trailers. The simplicity of the valve stem units is great and the internal band types are even better but of course requires dismounting and remounting/balancing the wheel assembly. My wife has been a victim of tire failure with horses aboard in the middle of summer and it's no picnic. Luckily there was no incident other than the normal pain in the butt misfortune. I highly recommend these types of products and having peace of mind on the highway is worth many times the cost of the system which I think is very reasonable for what the system does for safety. To go to the extreme, I carry a spare plus another spare should one tire take out another. Again, cheap insurance. etrailer has been great to deal with and I will continue to do business with this company as they are very customer oriented which is not the case with many companies these days.

I stand by my original comments of a year ago. Still a great product and they have worked as advertised. We have had two tire related problems that the pressuretemperature monitors detected before there was a problem. Highly recommend.

TPMS system was suggested by a friend who is a full time RV’er. System was very to install and seems to work as advertised. First trip is coming soon!


This is one of those items that is a must have. It's easy to install and setup. I also watched the product video and the spokesman was very detailed on programming. I would recommend watching it. I installed the repeater in the battery compartment located in the front of my trailer. It does not have a switch but you can unplug the inline fuse if your trailer is going to sit for some time. I trimmed the included rubber monitor support to fit the top dash tray for my Colorado.


I was having a difficult time setting up, called etrailer and they got me setup and understanding very quickly. Great customer service!


I purchased the TST system for our Airstream travel trailer after receiving several recommendations from other owners. After a year of use I’m very happy I took their advice. The system is very easy to set up and the cap sensors are not difficult to remove when adjusting air pressure. In fact, when you remove one the display’s alarm goes off within a second or two which is a good test of a fast leak. I did install the signal booster by connecting it to the Airstream’s running lights so I never have to worry about it. I used Velcro to hold the display on our RAM’s dash. Highly recommend the TST system and eTrailer as the vendor.


Used now on two trips and it seem to be working fine. External attachment to the stem for me was a factor. I didn’t want to deal with a tire service to install.


A must for anyone pulling a trailer. Early warning when tire pressure is low and before there's a BIG problem. Totally satisfied.


We used this TST TPMS on our cross country trip last summer, 11,087 miles. This was my second TST TPMS system and it performed just like the first one.....flawlessly! I think I need to quit letting them go every time I sell a trailer. I'm on my 3rd TST TPMS now, with yet another travel trailer toy hauler.


Package arrived but somewhat damaged during shipping. Have not yet tested the tst unit. etrailer support so far has been excellent.


Great product gives me a lot of comfort not to worry about my trailer tires after having one blow out and destroy the fender. I pull it with a Motorhome and cannot see the passenger side tires. It happened at low speed on a city street


I am very pleased with the TST TPMS. I pulled a 26 foot travel trailer nearly 8000 miles last year. The unit performed like it was supposed to with no problems. It was easy to setup and use. I would recommend this unit to anyone looking for a dependable easy to use system.


This thing is great. To start with, when preparing to leave for a trip, no need to crawl around checking pressure of 8 tires. Just turn it on and give it a few minutes to acquire all the tires.

Sure gives you a feeling of how tire pressure varies with temperature, too. More variation than I would have expected.


Excellent purchase, I feel more c9nfident rolling down the road with my camper knowing what the pressures of my tires are.


One of our first purchases when we got our “new to us” fifth wheel home. Having had two blowouts on the way home after buying (older tires and in storage for a while). We now have the peace of mind of always knowing ahead of time when there’s a problem. Easy to install and set up, works well.


Two huge positives. One, very accurate and matches my pressure gauge perfectly. The other positive, adds a lot of comfort and ease going down the road knowing what the pressure is without having to stop and check the tires. One negative but is minor. Twice I've had a false alarm, one time stating the tire was extremely overheated, and another time saying the tire only had 8 lb of pressure when it had the intended amount. Solution was simple, pull over, check the tire, and restart the system. One time I unscrewed the sensor, and then screwed it back, problem solved. The other time I simply unplugged the monitor from inside the cabin, plugged it back, and again problem solved. I would much rather stop and pause my trip for a false reading, than a tire change in a very difficult area.


Easy to setup and use. Monitoring tire pressure offers peace of mind and heads off potential tire trouble. Highly recommended.


Peace of mind! Must have for any trailer or Rv! Short trips, long trips, this keeps you informed of what’s going on behind you! Save yourself costly repairs and provide extra safety for the family!!


Installed this and 4 additional sensors on our 36ft 5th wheel and tow vehicle. Works great and not one issue! An investment in our safety when hauling a 12,000 pound camper that is worth every penny.

Pefect! No issues with the product. Id buy it again.
Steve O - 12/28/2021


About 8000 miles and has worked great. In my Class A motohome. Did buy a hood to shield from sun glare. Worth the money. Have not needed to replace any batteries. Would recommend.


Easy to set up and install. Didn’t know I had one tire that was low but the alarm told me. Leaving for a trip and very glad they are going with us.


I had a blow out on my 3rd trip with my new travel trailer. I installed these and they work great. I take them off when I park the travel trailer for over a month. They are great for trips and keeping an eye on the tire psi & temp.

  • Can TST Flow Through Tire Sensors Replace Standard Sensors
    To replace the standard sensors of your TST TPMS for RVs # TST-507-RV-4-C you need the standard Brass Tire Sensors # TST-507-RV-S4, but you can absolutely upgrade your system to use the flow through tire sensors. I recommend doing this because you don't have to remove flow through sensors to add air to your tires, making it much easier. To add 4 of the flow-through sensors you need to order a quantity of 2 of the Flow Through Tire Sensors for TST TPMS # TST-507-FT-S2. It sounds like...

    The TST TPMS for RVs part # TST-507-RV-4-C is a very useful device that not only allows you to monitor tire pressure but also tire temperature which is a big one. It will work just fine on a boat trailer as well even if submerged under water. I will say that the device will help to monitor hub temperature but not as directly as it does for the tires. I am however not aware of any such device specifically for the hubs so this is your best option.

  • Are TST TPMS Valve Stem Sensors Likely to Be Damaged By Road Debris
    I spoke with my contact in the Technical Services department at Truck System Technologies (TST). I'm told that the likelihood of either the standard or flow through sensor being damaged by road debris is pretty remote. The flow-through sensors will sit quite a bit taller than the cap style sensor, about 2-1/8 inches versus 7/8 of an inch for the cap style, so theoretically the flow through style would be a bit more susceptible to damage.

    You do not need to combine the tire pressures of an axle when setting the low pressure alarm of the TST TPMS part # TST-507-RV-4-C. So you'd base the low and high pressures based around 65 psi and not 130. So maybe around 58 psi instead of 117 psi.

  • What Alarm Setting Should Be Used When Setting Up TST TPMS for RVs
    In regards to the TST TPMS for RVs like part # TST-507-RV-4-C, the high temperature alarm setting of 158°F should remain unchanged. The high pressure alarm should be set at 20-25% over your normal tire pressure and the low pressure alarm should be set at 10% below your normal tire pressure. If you like, you can reach out to the trailer tire manufacturer to see if they have any other figures you can use but these will work for the majority of tires.
