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.

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.

- TST-507-RV-4-C

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.

- TST-507-RV-4-C

We've had this TPMS on our Airstream for a year. It was simple to hook up, and provided great piece of mind on our trip from Indiana to Colorado. It's amazing how many RV's you see pulled off to the side of the road on these long trips. We didn't notice any bending of the stems on our wheels over a 3000 mile trip. Display was accurate when checked against our tire gage. You'll be surprised how much pressure gain you can see leaving a site on a cold morning and driving into the heat of the day. Only drawback on this product is a somewhat dated display. Highly recommend!

Follow up after a year. The TST system has protected us over 5000 miles. Head unit easily finds the sensors, and we get great piece of mind knowing where were at with pressure and temps. The system even caught a slow leak long before it could have turned into a mess. We have a 25 ft Airstream, so a tire blowout could be very damaging. Changed batteries on the sensors when we got our RV out of storage last week- thats the only maintenance weve had to do. Highly recommend the TST TPMS.

On advise of a long time friend, I purchased this product for my 2019 Outdoor RV. On a 2000 mile trip to Yosemite NP, I was able to monitor the pressure and temperature of my travel trailer tires. Easy to install and operate. One small issue is the reported pressure on the monitor was actually 4 psi below what I measured with two pressure gauge devises. In all, I drove with confidence that if a tire failure happened, I would have early warning and time to safely respond.

- TST-507-RV-4-C

Towing an rv is stressful enough. TST TPMS gives me the peace of mind that my tires are operating properly and safely

Its working Great!

The TST TPMS sensors we placed on our travel trailer tires have worked reliably for the last year enabling us to monitor the pressure. I recommend these monitors for RVs.

- TST-507-RV-4-C

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.

- TST-507-RV-4-C

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.

- TST-507-RV-4-C

I have owned the TST TPMS on my 5th wheel for a little over a year. I have had no issues with it what so ever and would buy it again. I like fact that I can monitor both heat and pressure of the tires and adjust pressure and vehicle speed accordingly. Cheap insurance policy.

- TST-507-RV-4-C

Installed these on my 26ft Airstream one year ago. They have logged 18K miles and endured weather extremes from the blazing high plains of South Dakota in July to frigid Montana snowstorms. Have not yet replaced the batteries. No issues whatsoever. I did install the repeater though the monitors transmitted just fine without it. The only (very) minor annoyance is the inability to turn off the receiver/display unit when charging.

- TST-507-RV-4-C

This system worked perfect. Although it came with a windshield mount the dash mount fit perfectly on my F-250. It was easy to program and worked perfectly on our first trip. It was great not having to wonder about the tire pressures.

- TST-507-RV-4-C

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.

- TST-507-RV-4-C

You have to have this TST TPMS it will let you know in a hurry about the status of all your tires!

- TST-507-RV-4-C

Good product. I’m able to watch trailer tire pressure and temperature. Had one time we didn’t have one sensor on properly and tire lost 10 lb of pressure over several days, but it alerted us to to the lower pressure. Really gives us peace of mind knowing the status of the tires while traveling. Before buying these I was always paranoid about the tires having had blowouts previously. Really good product and worth the money.

- TST-507-RV-4-C

This system works incredibly well. It's a cheap insurance policy when you think of the damage a blown tire can do to a camper or boat trailer. The battery life of the tire sensors has been impressive.

- TST-507-RV-4-C

The TST tpms has been a great buy. It has been a great addition for safety and reducing stress while pulling my Cedar Creek Hathaway 34IK. Being able to watch the temperatures and pressures of my tires while traveling makes it one less thing to be concerned about. Absolutely would recommend TST product for anyone who wishes to tow safely.

- TST-507-RV-4-C

Having the peace of mind of knowing your tire pressure/temperature makes traveling more enjoyable than before. A must for towing our camper. Easy setup and monitoring.

- TST-507-RV-4-C

A fellow camper recommended installing a tire pressure monitoring system after I had two blow outs on the same trip, one of which, caused $1,500 in damage to our travel trailer. In addition to upgrading my travel trailer with Goodyear Endurance tires (one-year later with no issues), I purchased and installed the TST system for our trailer. So far, the system has worked as advertised, was easy to install, and I now have some piece of mind when we're on the road.

- TST-507-RV-4-C

Everything was as described on the website. Coming to Canada I was a little sceptical of getting the system through the border and the timeframe allowed but everything turned out well. A little slow getting here but everything went as described.

- TST-507-RV-4-C

Easy set up, worked flawlessly on our 1300 Mile trip. Great peace of mind being able to monitor the tire temp and pressures.

- TST-507-RV-4-C

This TPMS is far to complicated for just 4 or 6 wheels. Temperature monitoring only monitors outside ambient temperatures and is useless.

- TST-507-RV-4-C

Item was shipped promptly and in good condition at considerably less $ than available locally.

Relatively easy set up and installation. I used it several times in 2020. I love the peace of mind. I have had a monitor stop sending a couple of times even with the booster on my 26 foot double axle trailer. NBD really. The caps are a bit of a bother to remove to air the tires but not bad. I will get metal stems next tire change.

- TST-507-RV-4-C

Consistent readings across the four tires. One reading is always two pounds under the other three so I can tell that none of the tires are losing air

- TST-507-RV-4-C

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.

- TST-507-RV-4-C

I'm not a "gadget freak" and actually trying to simplify my life at this point, but I'm almost ecstatic about how well this system works! After buying my first pick-up truck at age 60, we were finally able to take our 24' travel trailer on out-of-state trips where traversing multiple hills/mountains would be called for. After having been saved by the vehicle's TPMS when returning from a local camping trip last summer after one our 2002 Jeep Grand Cherokee's new tires was punctured by a metal shard, I'd made a firm decision to buy a system to monitor the trailer tire pressure given the severe damage (or worse!) that would likely occur if a trailer tire were to fail while traveling at interstate highway speeds. I chose this particular system after researching various systems as well as evaluating numerous customer reviews. After studying the manual which I'd downloaded before ordering it, I was able to quickly get it set up and "installed" after it was received. Put simply, I literally couldn't be more pleased with how well it works. I opted to use the silicone rubber stand to position the display/control unit in the center dash-top well of our new F250 crew cab diesel, as I already had an Escort 360 and Garmin Nuvi hanging out on the windshield. The receiver was able to consistently receive the transmissions from each of the cap sensors without having to use the repeater, and the display was clearly visible even when I was wearing sunglasses during midday driving under a cloudless sky. I've always prided myself in monitoring my vehicle's dash gauges while driving to help ensure that I'll at least have a chance to preempt an unnecessarily disastrous situation from occurring, so the ability to accurately monitor the pressure and temperature of all four trailer tires without posing an undue distraction while driving is arguably some of the best insurance that I could buy. Of note is that I opted to purchase a system with cap sensors instead of flow-through sensors since the cap sensors have much less mass (i.e. they're much lighter) and therefore more suitable for use on wheel rims with rubber valve stems.

This TPMS system is still working great, and I havent even had to replace the batteries in the cap sensors yet. I decided to recharge the battery in the control unit for an upcoming trip, so I took the control unit upstairs in our house and plugged it into a 12 volt power supply. A short time later when I checked on it I was amazed to see that it was displaying the outputs from 3 of the cap sensors on the trailer thats parked out in our back yard! Without a doubt this is a system that I strongly recommend to anyone who owns a travel trailer.

    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.

    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.

    I suppose it is possible for the batteries to be dead in your new sensors but this is unlikely. However, I took a look in the manual for the TST TPMS for RVs part # TST-507-RV-4-C and on page 5 it states the following: "Note: If a double beep is heard and the “FFF FFF” does not change, try quickly pushing the “CODE” button once again. This may have to be done a few times for the code to appear. If the sensor does not code, check the battery voltage, be sure other sensors are not close...

  • Low Pressure Alarm Setting for Tire with 65 Max psi Rating
    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.

  • Correct Method For Adjusting Tire Pressure On Long Road Trips
    TPMS systems, such as TST TPMS for RVs - Color Display - Signal Booster - 4 Tire Sensors # TST-507-RV-4-C, are usually very accurate in determining the tire pressure in your 5th wheel trailer. The correct way to set tire pressure is when the tires are cold before towing. It is normal for road heat to increase tire pressure and that is usually not a cause for concern so you wouldn't need to adjust after driving. However, if you are going from cold climates to extremely hot climates like...

  • 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.

  • How To Prevent Blowouts from 235/80-16 Tires On 5th Wheel Trailer
    There are several factors that can cause a tire to come apart, the most common of which is heat buildup. The best way to prevent this is to closely monitor the tire pressure and temperature which can be done with a TPMS. I recommend the TST TPMS for RVs part # TST-507-RV-4-C which features simple screw on sensors and a dash mounted monitor. This system will allow you to set alerts so you can be warned when temperatures/pressures are in conditions susceptible to a blowout. In regards...

  • Deciding Between Flow-Through and Cap Style TPMS Sensors for an RV
    If you have valve stems with a metal body like the Americana Metal, Bolt-In Valve Stem part # AM20906 then you will want to use flow-through sensors but if you have valve stems with a rubber body like the Americana Rubber, Snap-In Valve Stem part # AM20903 then you will want to use the cap style sensors. The TST TPMS for RVs part # TST-507-FT-4-C and part # TST-507-RV-4-C are my recommendations.

  • Recommended TPMS System for 40 Foot Long 5th Wheel Trailer Pulled by Long Bed Crew Cab Truck
    According to the folks at ASA Electronics, due to the combined length of your fifth wheel and truck the # NCTP100 iN-Command TPMS system wouldn't be the best choice for your setup. The system would work perfectly on your truck tires, but performance would be inconsistent for your 5th wheel, especially for the back axle. We do have a system that would work very well for you though. I'd recommend the # TST-507-RV-4-C from Truck Systems Technologies. This system provides 4 theft resistant...

  • Is TST Tire Pressure Monitoring System Color Monitor Compatible with EEZ Brand Sensors?
    Yes the Color Monitor for TST TPMS Systems # TST-507-D-C is the newest monitor. It is not interchangeable with the EZZ RV tire pressure sensors as they are different brands so the transmitters and receivers are different. You'd need to get the entire system for compatibility.

  • Is TireMinder Smart TPMS Compatible with Sync 3 Bluetooth in 2018 Ford F-250
    From what I could find it doesn't look like the Sync 3 system from Ford will support the TireMinder App just yet. You may still be able to use the TireMinder # TPMS-APP-4 that uses the Smartphone display but I don't think you'll be able to utilize it with your 2018 Ford F-250 unless you are somehow able to install the app on your truck. If you can't download the app and/or it doesn't work with the Sync 3 then we have the TST System # TST-507-RV-4-C which uses the standard sensors or...
