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 flow through sensors that attach to the valve stems of your tires. The flow through design lets you inflate or deflate your tires without removing the sensors. 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. Screw the anti-theft hex nut onto your tire's valve stem threads until it bottoms out.
  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 seat the sensor while being careful not to over-tighten.
  3. Use the included wrench to tighten the hex nut counterclockwise until it is snug against the sensor.
  4. Screw the tire's valve cap onto the sensor.

Note: To inflate or deflate a tire it is not necessary remove the sensor. Simply unscrew the cap.



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.

I have been looking for a TPM system for my 40 foot triple axle fifth wheel. I had a blowout last fall and it caused damage to the camper. This will remedy that situation. In the spring I'm going to have 14 ply tires mounted on the rims and the tire pressure sensing system will be added to the camper.
Very happy with how quickly the system was delivered to my home. It's just what I was looking for.



Very happy,they work great and help keep us safe.


I like this very much. We use it on our RV when towing and I keep it in my car ( The tow vehicle) the rest of the time. i wish I could use the flow through sensors on my car tires. The sensors are a bit difficult to put on and off.


The TPMS system works well. I had 6 on the RV, two on the car, and two on the tow dollie. The sensors are not 100% accurate but give a rough idea of pressure in the tire and temp. Always have an appropriate tire gage to get true pressures. The system did save us in NM because the potholes were so bad we broke a valve extension and an inner rear tire went flat quick. The monitor caught this and saved us a blowout. I just wish the sensors were 100% accurate otherwise it's a great system.


Setup was easy enough that a non-techy person can do it. Readout is clear and seems to be fairly close to my tire guage. Within 2#s variance. I have never exceeded my alarm limits, so I'm not sure how loud the alarm is. I consider this cheap insurance. I have replaced the batteries twice a year as part of my trailer inspection and maintenance cycle. I would definitely recommend to anyone who tows.



After 2 full seasons of towing, I have had absolutely No issues with these. They hook up flawlessly ever time and give me piece of mind on the longer hauls. I would recommend using this system on any rv that gets used regularly. I have seen a couple of accidents due to rv tires exploding and both were totals. A really good way to screw up a vacation.


Purchased this tst system about a year ago, installed it on a 2017 ForestRiver Forester on a E450 chassis, my very first trip with this system installed save me from ruining a brand new tire that had an improperly installed vave stem that came loose, the system detected a fast leak, I was able to pull of the highway and call the people who installed my new tires to come and fix their bad installation, would highly recommend this system

Al H.


Great, as I stated in my first review it save me from ruining a brand new tire because the tire installer didnt secure the metal valve stem properly,I would not leave on a trip without it, great product, my only gripe is I didnt any O rings when replacing batteries, would purchase this very system again


Easy setup, and the trailer tires show up as well. I love how it shows the RV separate from the trailer


Works very good! Feel better about having a system that can assist you in keeping an eye on the tires for both the RV and the towed vehicle. My only complaint is that we have had a few false warnings of either temp or pressure warnings that required me to pull over to make sure that all is okay.


Friendly, pleasant, quick & knowledgeable describes my experience with Paul, the sales rep., when purchasing a tire monitoring system from etrailer. Highly recommend.

The product, tire monitoring system, shipped fast, arriving just when needed. It is of excellent quality, had clear instructions and was easy to install. With out a doubt would buy this product again.


Works very well. Picked up a nail in one of my rv tires. Sensor notified me when pressure dropped to low. Saved a tire blow out and possible damage to my fifth wheel.


Great product



Love it. It save me recently. Tire started loosing loosing pressure and I got to the side of the road ASAP. I highly recommend this product.

@Timothy We're glad to hear that, thanks for checking back in!


I finally got a chance to use the trailer which has the sensors. It was great to find out the tires had lost air.

I was concerned about the sensors sticking out too far and possibly getting damaged when changing the tires. I decided to use the 90 degree valve stems. This was a mistake. The pressure on the valve, because of the leverage of the added length occurring with the TST sensor installed, cause the valve to leak at the rim. We changed all the valve stems to the short straight stems and now do not have a problem maintaining the tire pressure.

We have travelled to FL from NJ and to IA, NY and back. The sensors work great. You set the pressure notification value and when the air goes below that value a beep starts. The display does a continuous scan which is easily seen if you put it on the dash. I would definitely buy this again.


Our experience with has been outstanding. In both cases, the product was delivered on time and marched the product literature. We highly recommend and will continue to source our part needs with them. Thank You!


Performs as advertised. Was what I was looking for. Can't have enough information about my rig's condition when I'm rolling down the road. Cheers!

Robert Y.


Still doing the job, no problems.


I did not like the TPMS. The display was too distractive. Driving the RV needs full attention but the TPMS created unnecessary distractions, usually about insignificant info.
Also, the wheel sensors are too heavy, which caused the valve stem on one the wheels to break off.
I have removed the system from my RV.


These have worked flawlessly for the last year. Periodically I check the pressures with a digital pressure gauge and these are right on when I do so. Good not be any more pleased. I do plan to add sensors to my towed vehicle as well in the near future. I have not needed to use the signal booster with the original 6, but will likely need to once I add the 4 for the towed vehicle.


Tpms works great! It has saved us twice from slow leaks. Only thing I would caution- there are washers with your kit that you put on before you put the sensor on. Don’t skip that step! We don’t remember seeing it in the manual but those washers prevent slow leaks from the sensor. Luckily we were able to learn this from a fellow camper before replacing a tire!


I installed this system on my class C motorhome. It saves having to verify tire pressure with a hand gauge and piece of mind that I don't have a leak on a dully tire while driving. You cannot feel a low or even totally flat dully tier, resulting in total shredding of that tire doing damage to the vehicle. This system was easy to install, keeps me informed on tire pressure and temperature. Instructions were easy to follow.


TPMS setup and function reliably. The alarm is loud and cannot be missed.
But the display is weak and must be shaded to be seen. Disappointing as it is mounted next to my GPS, my ScanD, my backup camera and those are all easy to read
I did have one sensor fail and was very impressed by the assistance and speed of replacement.



Loving it. Now added fir the trailer. Just ordered a now-available sun shade from TST


Except for one miscue with a sensor, everything has worked fine and is a good system. 1 sensor gave me a heart attack going down the highway when all of a sudden an alarm started sounding. In a motorhome there are many alarms, when i finally located it, the sensor said 1 tire on the towed car was @ 325 degrees. I reset the receiver and all is well. Good system.


Worked as advertised. Purchased an additional 4 sensors for our towed vehicle. The system accommodates multiple configurations of vehicles and trailers which supports my original plan to alternate between a towed car and a trailer. Once all are programmed in, it is easy to switch configurations.

Still working great and no need to replace batteries. I took the 4 off of the Toad for the winter, reinstalled them this spring and everything is working great. A definite must have for both the Coach and especially the Toad.


This system is replacing another which did not work with my rig. My previous system worked good on my 34ft tandem axle trailer but was lacking with my 43 ft triple axle rig. The TST was easy to install and calibrate. They arrived fast and at a great price. I have recommended this system to all my other traile4 owners with no hesit.


The TPMS RV system works as advertised, I have a 3 axle 5th wheel. I did have an issue with one sensor leaking, etrailer got right on it and sent another one out to me. I do like the system, and the battery life of the receiver unit is outstanding. I recommend this products.


This is my 2nd purchase as left the 1st on a previous rv. TST 507 gave me good service for 9 years and i am sure this new set will do as well. Also. I feel secure dealing with Etrailer. 8 years ago I purchased a camera monitor thru etrailer that had an issue caused by the manufacturer. A lady at Etrailer. whose name I can't remember. totally went out of her way to make me happy. There were other purchases that went well in all phases


I really like the display and the ability to program multiple sets of sensors as I own several trucks and trailers. Its nice to be able to tell at a glance what all of my truck and trailer tires are doing temperature and pressure. I had a valve stem lock nut come loose and start leaking, saw the pressure drop on that tire and the temperature increase on the other axle, got off the road and repaired before I had a blowout and all of the trailer damage that comes with it. It paid for itself on that trip alone. I have since bought more sensors for my other trailer and for my other truck. Highly recommend it.


We purchased the TST 507 TPMS for our 30 foot class B+ motor home with the additional 4 sensors to install on our Jeep Wrangler toad. I had to slightly alter the 16” steering tire Stainless wheel covers to make room for the air through sensors. The dual rear wheel covers installed without any sensor interference.
Once I got into a patterned routine I was able to program the 10 sensors without any problem. At first I programmed the high pressure too low and the high pressure alarms went off. I reprogram to 10% above the maximum tire pressure and the system works flawlessly. After loosing several China bomb tires over the years on travel trailers We now travel in confidence that we aren’t going to have tire catastrophes.
