Tire Sensor Installation

Tire sensor Install Diagram

  1. Place the included wrench around the sensor. You must use the wrench to put on 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.

These sensors let you monitor 4 additional tires with your TST TPMS, or you can replace lost or damaged sensors. Theft-resistant covers require the included cap wrench for installation and removal. For use with rubber, brass, or steel valve stems.


Really nice having enough sensors for truck and trailer and setting up ensure is very simple ! So far great product


Replacing a set without exchangeable batteries. Easy to set UP with TST MONITOR.


The wrench that you use to tighten the sensors is awkward to keep straight. It slips out of place easily.


The TST monitoring system works great, but be advised there IS a bit of programming / trial and error involved in getting the thing commissioned ... but once it is working, it is a very good accessory for the safety of travel trailers. Overall, the TST instructions could use a bit of improvement to make them more user-friendly. As usual, etrailer delivered on-time!


After a year of using the TST tire pressure monitoring system, I am very satisfied. It has worked on my truck and trailer in all weather and always alerted my of any low pressure condition. I would buy it again and would strongly recommend it to a friend.


works well use it every time we take the travel trailer.
set up was harder than I thought it should be. Great accessory to have.


Saved me a flat when towing!


We have them on our western star HDT and on our DRV 5th wheel...they work great as Advertised...I would recommend etrailer and tst tpms..


I have these installed on my 41' fifth wheel and while traveling on interstate 80 in Pennsylvania My alarm sounded.
I immediately pulled of the road and found that I had picked up a piece of steel. (ruined the tire)
With the alarm sounding so quickly I saved running the tire flat and possibly doing more damage to the trailer other than just replacement of the tire. The monitoring system worked so well when I returned home I ordered sensors for two additional trailers that I pull.
I would highly recommend this product to anyone that pulls a trailer.


I have used TST tire pressure monitor sensors for about 7 years on pickup, fifth wheel, motor home, and toad. I purchased additional TST tire pressure monitors for my motor home to replace the flow through type. I had the flow through type and found the amount of air they let in to fill the tire was too slow. The price was competitive. I was kept informed of the shipping, but it took a couple weeks to get the item. The item arrived in perfect condition and all the sensors work like they should.


This sensor pack is perfect for the trailer so both truck and trailer tires are monitored, to provide information before a situation becomes much worse.

Chris N.


One year later and the product is still great. The tire monitoring system has been working perfectly and allows you to confirm tire pressures are good, if something feels a little off. In the event of low pressure, you are alerted to the situation before it becomes a big issue. This is a must have product for vehicle and trailer. ETrailer has been oustanding to deal with for a number of purchases, provide great sales and product support.


Easy to assemble and manage tire pressu re.


Fast service exactly what I ordered


Love them! I bought these to add to my RV TPMS to allow me to monitor both my truck and my 36ft 5th wheel RV, for a total of 8 sensors. Worth the price to help ensure the safety of your rig and the precious family cargo inside!


etrailer had the best price for this product and it was shipped and received in a timely manner. I am very impressed by the TST pressure management system and use it for both my truck and 5th wheel.


Once again I am very impressed with e Trailer. I am a Canadian customer and have found the prices including exchange to be lower than options here plus the delivery had been remarkable fast on both orders I have made.



A year after purchase and I am even more impressed than I was at first. A definite 5


Same as above..


Works great. Small enough to be safe with rubber valve stems. A bit of a pain to add or remove any air but well worth the effort


Very good product. Lots of piece of mine GOING down the Highway to know my tires are at the proper inflation.

Bill S.


Product is working GREAT


Needed these to cover all the wheels between the truck and camper


Great product and great customer service. Amy went above and beyond to help me get my order correct for my application. Will definitely be a returning customer. Thanks.


Great product! Arrived on time! Good install video!


Fast friendly service as always....thanks bunches!!


Bought these 4 for our toad to work with the coach pressure readout. Worked great!


These Tire pressure sensors, were received 3 days after ordering, which was great. The sensors are installed and working, took a matter of minutes to install.
These are replacing the flow thru type, it is my experience that these cap type sensors give a quicker response then the flow thru type sensors. Also these cap type are shorter then the flow thru type, making them less likely to get broke off.
etrailer is a great company to deal with, they follow up by keeping the buyers informed on shipments, and they want their customers to be satisfied.
I will continue to purchase from etrailer.

  • Can A TST TPMS System Be Used To Monitor 14 Tires?
    The TST TPMS System # TST-507-RV-4-C can be used to monitor 14 tires. This system can support up to 38 tires total. The monitor will allow you to cycle thru all 14 tires. You will need to purchase additional sensors, as this kit only comes with 4. Additional sensors are sold in a 4 pack # TST-507-RV-S4 or a 2 pack # TST-507-RV-S2.

  • Can Additional Sensors Be Added To TST 507 TPMS System?
    Yes, you can add the Brass Tire Sensors # TST-507-RV-S4 to your TST TPMS # TST-507-RV-4-C to be able to also monitor the tires on your truck.

We do also have the Internal Tire Sensor # TST-507-INT-S1 if you are concerned with the other sensor from being stolen.

  • Can Valve Stem TST Sensor Replace Internal Sensor
    Since your display is the part # TST-507-D-C the valve stem sensors like the # TST-507-RV-S2 can be used with it. The internal sensors we also offer with part # TST-507-INT-S1.

  • What is Difference Between TST Tire Pressure Monitor Systems # TST-507-FT-4 and # TST-507-FT-4-C
    The two kits you mentioned are basically the exact same with exception being the color of the display. The # TST-507-FT-4-C has the color display that puts the alert messages in red if there's high or low pressure as well as temperature whereas the gray scale # TST-507-FT-4 would display everything in the same gray-like color. Either kit works great on rubber valve stems. For the second trailer you'd need additional sensors with # TST-507-RV-S4 and you'd be able to use it with the same...

  • Adding A Trailer Tire Pressure Monitoring System To An Existing Motorhome System
    The # TST-507-FT-S2 will work though these cannot be used on rubber stems and you will have a higher chance of curbing because these stand out a bit. I did contact TST who recommended the Brass Tire Sensors for TST TPMS - Qty 4 # TST-507-RV-S4 as a better solution that addresses those concerns. Either will work for you but I wanted to make sure you're aware of your options. Included are review videos for your review.

  • Recommended Tire Pressure Monitoring System with 12 Sensors
    The TST TPMS for RVs - Color Display - Signal Booster - 6 Tire Sensors # TST-507-RV-6-C are a great choice for your Class A and trailer. This company actually started out making TPMS for tractor trailers, so these are extremely durable and I really like the color monitor on the system since it's easy to read. Because of the length of the two vehicles I do recommend adding the Signal Booster # TST-507-R. Since the kit comes with 6 sensors you will need 6 more which can be added with #...

You do have the option of what sensors you will prefer to use from the list below.

  • 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...

  • 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...

  • Will the TST-507-RV-6-C Work on an RV/Toad That is 68 ft Long Overall?
    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. Since there is not a pack of 12 sensors available, you'll...

  • Are Aftermarket TPMS Sensors Compatible With Factory In-Dash Monitors
    The TPMS (tire pressure monitoring systems) wheel sensors we offer, such as the # TST-507-RV-S4 you'd looked at would used their own monitors, and wouldn't be compatible with the factory in-dash monitor on a Ram truck. The sensors you'd looked at would be included with a kit like # TST-507-RV-6-C which would include 6 sensors, the color monitor and the signal booster. I've linked to a demonstration video featuring the # TST-507-RV-6-C TPMS system.

  • Compatibility Of TST TPMS Brass Tire Sensors On Rubber Valve Stems
    Yes, the Brass Tire Sensors # TST-507-RV-S4 and the sensors that come with the TST TPMS for RVs # TST-507-FT-6-C are compatible with your valve stems. These sensors are compatible with rubber(brass), steel, chrome, or nickel valve stems. They should not be used with aluminum valve stems as that will lead to damage of the sensor as the 2 metals are not compatible and will corrode each other.

  • Using TST TPMS on RV that Tows Honda CR-V or Trailer
    I reached out to my contact at TST regarding their TPMS systems for your particular application. First he said for your setup it will be best to mount the signal booster in the RV towards the back of the coach. He recommends going with the Color Display TPMS # TST-507-FT-6-C because it will allow for an easier setup to program it for both your Honda CRV and trailer. He said this can absolutely be done and after the initial programming it's just a matter of pushing a couple buttons when...

Extra sensors are available in a quantity of 2 as part # TST-507-RV-S2 or 4 as part # TST-507-RV-S4. The sensors provided are compatible with rubber, steel, chrome or nickel valve stems.

  • How To Add Additional Sensors to the TST TPMS for RVs TST-507
    In order to add TPMS sensors to your tow vehicle to use with the TST TPMS for RVs part # TST-507-RV-4-C you will also need the Brass Tire Sensors for TST TPMS part # TST-507-RV-S4. The only other thing I recommend for you is extra batteries, the Replacement CR1632 Batteries part # MRI-CR1632. The above will include everything that you need to get setup and hit the road.

  • Recommended TPMS Sensors For A Motorhome And A Flat Towed Jeep With Rubber Valve Stems
    The flow-through sensors included with the TST TPMS for RVs # TST-507-FT-6-C you were looking at are not compatible with rubber valve stems, and the sensors for rubber valve stems not compatible with this specific system so you would need to use kit # TST-507-RV-6-C and get an additional 4 sensors # TST-507-RV-S4 for your Jeep. Flow through sensors are definitely convenient but are heavier and can end up bending and damaging the rubber valve stems on your Jeep.

  • Recommended Tire Pressure and Temperature Monitoring System for 2018 Grand Design Solitude & Trailer
    For your 2018 Grand Design Solitude the factory temperature sensor for high temp is 158 degrees. This is based on the Michelin Standard for tire temperature. It is the same for all size tires. Usually a tire will not expand enough to blow until it reaches between 170 and 200 degrees. This alarm should give you enough time to pull over to let the tires cool down before there is a major issue like that. Although your tires will heat up at different rates, this is a fairly good place for...

  • Is There a Correct Valve Stem Length For Installing TPMS System
    The 3/4" of valve stem that's exposed for your setup will be adequate to accommodate the flow through sensors found on the TST TPMS for RVs # TST-507-FT-6-C or the cap sensors found in the kit # TST-507-RV-S4. The manufacturer, TST, recommends installing their system on a metal valve stem like the part # AM20906 which measures 1-1/4" for what's exposed but aside from that they don't really have any guidelines on valve stem length. Really just as long as all of the threads for the valve...

Since you already have some, you could remove them and test fit them first. Pretty much all valve stems have at least some rubber on them, more than likely...
