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.

Saw these on YouTube and knew the necessity as my brother, a long-haul truck driver and 5th wheel RVer, says TPMS is a MUST. I have 6 wheels on my 5th wheel and just got 6 new Michelins on the pickup. I now have my pickup, 5th wheel, flatbed, and all of their spare tires monitored. Peace of mind is a wonderful thing when going across Wyoming at 80mph in 100 degree heat.
(Update) 70K miles in 8 months and this TPMS system is spot on. Thank you to etrailer.com for getting the correct sensors for my system in a fast and efficient manner. Great service at a great price. Very happy with my purchase.

One year of safe travels with my TPMS system for my pickup, 5th wheel and flatbed trailer. Travel is so much more satisfying when I don’t have to stress about the tires.



by:

I've used the Roadmaster Hitch Mounted Spare Tire Carrier for the last year (2023) and have put over 7500 miles on it. The carrier has performed seamlessly and is still manageable when mounted 40 plus inches off the ground. I have it attached to a Torklift 5' extension that goes into a 3" receiver welded into my flatbed. To prevent bouncing I've had Torklift put in a support bracket from the lower(regular) receiver. No bounce!



by:

Does exactly what it needs to do. There was an issue with the hubcap opening not allowing installation. Had to use valvestem extensions to facilitate installation.



by:

Matches sensors received in a recently purchased tire monitoring system.



by:

Needs metal valve stems which etrailer representative says the do not sell. They are listed on their web site. After getting nowhere with etrailer representative decided to return these flow sensors. Not worth the hassle.

I apologize for any miscommunication that happened. Part # AM20906 will work together with part # TST-507-FT-S2. You just have to make sure your tire is one that is rated for a PSI that is over 100. The rim would need to have valve stem holes that are 0.453 or 0.625 inches in diameter.



by:

The weight of these add-on sensors flexed the valve stems on all four trailer wheels. Two of the four went flat during the trip. The other two I could pull the core out after we got home. The flexing caused heat in the rubber parts and disconnected the inter mail tube from the rubber. There should be a “steel stem only” notice on the product listing.



by:

I purchased this a year ago and finally installed the system prior to a long trip with my camper. Once paired the system gave us an additional sense of security as we traveled. Great product.



by:

I purchased 6 tst internal sensors for our RV with the color monitor. I also purchased 4 flow-through monitors for our jeep, which we tow. The products are awesome and saved us from destroying tires on the RV. On RV’s with dual tires in the back, the inside tires get extremely hot in high summer time temperatures. The sensors taught us not to drive when ambient temperatures are 95 or higher. We have read where numerous RV’ers have had catastrophic blowouts on inside dual tires and our tst sensors allow us to avoid those dangerous situations. We absolutely feel the product should be installed on all R’s and trailers.



by:

Would not be without a TPMS on my RV. This system has worked flawlessly. As a reminder, make sure you replace the rubber valve stems in your wheels with metal ones before installing these sensors.

One year later and could not be happier. We are full time on the road in our RV and depend on this system to alert us if we have a tire going down before we see the smoke and damage in the rear-view mirror. Over 5 years on the road, we have lost some tires, but none sense we installed this system.



by:

I have a 7 year old TST TPMS that had a misbehaving sensor. Advice from TST was to replace the sensor. eTrailer offered the sensors at a reasonable price, had them in stock and offered free shipping. The 2 sensors arrived earlier than originally estimated. Sensors have been installed and all is well in TPMS on my MH.



by:

They work great, gives tire pressure and temp. I have had the TST system for about 6 years now and the only reason I needed to replace these were due to the tire company putting them on too tight and broke them.

Garry H.

11/15/2022

Great, perform flawless, remove them yourself if needing tire work done, destroyed 2 of them with excessive tightening.



by:

Warned me of a double blowout on my triple axle boat trailer so I could get off the Florida Turnpike as soon and safely as possible without destroying the rims or damage the trailer and boat.



by:

Added 4 more sensors to our existing system and programmed them as a second trailer. 1000mi road trip next week, the system has saved us on our 5th wheel, and it will be nice to have piece of mind pulling our car trailer as well.



by:

The sensors provide valuable temperature and pressure information to the dash mounted display in a five second alternating pattern. That makes it easy to read the information without distraction.



by:

The only Tire monitor system to buy! we have them on our triple axle DVR Santa Fe and our M102 Freightliner tow vehicle.

These are extras. I have been using these for several years. They work great.I only had one false alarm. Rebooted recieverand all was well.

All is working well.



by:

Great system! I would recommend this to anyone who is towing a RV or trailer. It does a great job monitoring pressure as well as tire temperature. Should not be towing without monitoring your tires pressure and temperature. A happy user!



by:

Always get prompt and accurate service. etrailer keeps me informed regarding my order with emails and a direct contact should I have any questions. Thanks as always for great service.



by:

TST TPMS Flow Through Tire Sensors in my opinion are the best in the market place especially for rear duels on your coach. Easy to setup and maintain tire pressures. I have had this setup for a year. The TST display is second to none!!!!!!!!!!!!!



by:

Ordered these replacement sending units for the system on my motorhome. One of the existing senders went bad so now I have one as backup. Sending units had to be of the same brand of TST TPMS. Replacement was quick and easy although the locking system has changed.



by:

The TPMS for TST is overall very good. I have had the primary system for 5-6 years and it has always preformed well. However in the past year I have had 3 sensors quit working. I changed the batteries, moved them to different tire locations, even reprogramed them. The only thing that worked is replacing them. At $50 each its expensive. That makes my replacement half of all sensors on the RV. 6 in total and replaced 3. I am not unhappy but more irritated.
I also started with the black screen and upgraded to the color screen when it came out. I have sense gone back to the black screen. I cannot see the numbers being reported. I see that there is now a shield for the screen glare so I have ordered that from the company. So we shall see. Would I buy this system again? Probably not as I think the technology has improved and I am not sure where TST measures in.



by:

Like the new sensor!. Had to replace an older (set screw) model that got damaged. New sensor coded up first try, installed easy. Very much appreciate the new locking nut versus the set screw. To be honest I never was able to tighten the old style set screws on all 6 wheels anyway. The locking nut and tool give an added sense of security. Just installed today, so no long term assessment yet.

As usual excellent service and turn time by etrailer!



by:

Easy to use! Peace of mind on the highw ay.



by:

The TST tire sensors have saved our bacon on two separate occasions when we had a tire fail on our travel trailer. The big thing to remember for this product is the need for METAL valve stems. A definite must have piece of kit for on the road safety.



by:

Installation, and configuration is straightforward. I did have one sensor leak, etrailer replaced it immediately. So far I'm happy with them.

  • TST Tire Monitoring System With 12 Flow Through Sensors
    You will need the TST TPMS for RVs # TST-507-FT-6-C which includes 6 of the flow through sensors. For the other 6 sensors you are needing we have the Flow Through Tire Sensors # TST-507-FT-S2 sold as a quantity of 2. Therefore you will need 3 sets of the additional sensors.

  • Recommended TST TPMS System for 30 Foot Trailer and 2019 Chevrolet Silverado 2500 HD
    If your 2019 Chevy Silverado 2500 HD Duramax already has a built in TPMS, I don't think you'd need to add the additional sensors to the TST TPMS for RVs - Color Display - Signal Booster - 4 Flow Through Tire Sensors # TST-507-FT-4-C, but I would definitely consider it. The great thing about adding sensors to this system and not using your vehicle's monitor, is that you can monitor everything on one monitor, as opposed to two. The TST system has an easy to read monitor that can be setup...

  • Tire Pressure Monitoring System Recommendation for 2017 TIffin Phaeton AH Towing Jeep Wrangler
    Since your 2017 TIffin Phaeton AH has 6 tires and your 2021 Jeep Wrangler has 4 you'd want the TST TPMS for RV's part # TST-507-FT-6-C which is a system that comes with 6 sensors and then two additional part number # TST-507-FT-S2 which is a pair of sensors you can use for the remaining four you need. This will give you an accurate and reliable setup with a long reception range and since the sensors are flow through you can inflate/deflate the tires without having to remove the sensors.

  • Can I Use Metal Valve Stems with a TST TPMS System without Flow Through Sensors
    You could use the Americana # AM20906 on your wheels, but your TPMS system is not designed for metal valve stems unfortunately; those sensors can only be used with the brass/rubber stems. If you wanted to switch to metal valve stems you would need the flow through sensors like the Flow Through Tire Sensors for TST TPMS - Qty 2 # TST-507-FT-S2. If you check out the end of that video these valve stems are installed on a similar wheel, and I've linked that video for you to check out.

  • Recommended TPMS System for 2005 Ford F-350 Towing Fifth Wheel
    I'd recommend a TPMS system from TST, Truck Systems Technologies, because they're highly rated by our customers, they work great and their customer support is outstanding. To keep costs down, I'd recommend a system going with a system that used a grayscale monitor, versus the color. If you're talking TV's, color is the way to go but for a TPMS system a grayscale monitor would work just fine. I'd go with the basic # TST-507-FT-4 system, then add 4 additional flow through monitors, using...

  • Is There a Way to Monitor 12 Tire Pressures between RV and Trailer
    The TST tire pressure mounting systems can support up to 38 tire pressures monitored so for that you'd want to start with the TST TPMS for RVs # TST-507-FT-6-C which comes with 6 sensors and then add three sets of 2 sensor packs with part number # TST-507-FT-S2 and you'd be set!

    I spoke with my contact over at Truck Systems about the TPMS for RVs # TST-507-RV-6-C and those TPMS sensors will work for your RV, but he mentioned that you would likely want to use the system that has the Flow-Through caps instead, which can be found with part # TST-507-FT-6-C . This is the same exact system with the color monitor, but the caps will allow you to fill your tires without removing the TPMS caps if the need arises.

The kit comes with 6 sensors and you can add up to 38 different sensors allowing you to use the main unit with multiple vehicles and even load up to 4 different vehicle profiles.

    According to my research the TST Signal Booster / Repeater # TST-507-R won't work. People have tried different aftermarket solutions but none of them have been able to communicate with the OEM TPMS on the newer GM trucks as of yet. I read that GM is in the process of making one but we both know to take that kind of news with a grain of salt and not to hold our breath.

If you wanted to use the TST to monitor the tires on your F-250 as well then you'll need to install some TST sensors on your truck tires.

However, I did confirm with my contact at TST that you are able to mount the signal booster on the back of your pickup.

If the battery is dead or sensor communication is interrupted temporarily, lines or dashes "---" are displayed for that sensor on the monitor.
