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.

I needed to add 2 tire sensors as I am pulling a 2 axle trailer now. These worked seamlessly to my existing monitor.
by:
Easy to install and paired very easily to the TST monitor. Worked perfectly on a 2 week few hundred mile trip. E trailer was great to work with and answered all my questions prior to purchase.
by:
I ordered the flow through sensors and rec’d the standard sensor.
by:
These sensors work the same as the internal sensors but there is no worry of a loose sensor inside the tire.
by:
Excellent and friendly service!
by:
Easy to install and program. Thanks etrailer for prompt shipping and excellent customer service.
by:
Works as it should
by:
I have 4 TST sensors on our 5th wheel RV and wanted to add 2 sensors to the rear wheels of the tow vehicle. Our truck has pressure monitoring but not rim temperature and alarm for loss of pressure. The TST sensors take care of that and have been reliable. The new display is a nice upgrade to the older version.

After a year of using the TST system on our truck, we still feel that they provide temperature and pressure readings necessary for a higher level of safety. We tow a heavy fifth wheel camper and also have sensors on the 4 wheels of the camper. Thanks TST for providing a quality system.

by:
My previous tire sensor TST 507 had over 69k mileage, but I broke it. Absolutely love these tire monitors!
by:
Senors worked well as expected
by:
Bought these for my car to monitor the tires when towing behind my motorhome. They have worked flawlessly. Delivery from etrailer was on time. I will buy again if needed. I have always been satisfied with my purchases from etrailer.

They are still working great!

by:
Easy to install and program. Very reliable. I have a sensor on each pickup and trailer tire.
by:
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.
by:
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.
by:
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 trailer? 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.
by:
Unit has been running for approx 1 year on the original batteries. I am monitoring 6 wheels on a RV and 4 wheels on a tow vehicle. My only minor complaint is the screen brightness. It appears to be brighter unplugged than when it is plugged into a 12V supply. This seems backwards to me. I like a bright screen but either one is readable.
by:
Tire sensors work well and keep me informed as I travel. The remote repeater is a must have for a long coach.

The TPMS is still working well. Lets me know if I need air before traveling in the am.

by:
Sure gives me piece of mind to see the tires temperature and pressure on my RV and towing vehicles. This is after experiencing a tire going flat and not knowing it.
by:
Excellent technical support. Made sure I ordered the correct product to work with my existing TPMS system. Product arrived close to a week sooner than original estimate. Always top notch service when dealing with Etrailer.
by:
Didn’t get to try out the sensors...unknowingly my RV was already equipped. But as usual, I’ve always had professional, competent service at Etrailer.
by:
Great product. Great service from etrailer.
by:
Easy to program and work great with my TST 770 display.
by:
These worked fine, however I replaced them with the pass-thru version in my RV. Reused this on my tow dolly.
by:
Great service
by:
It's been a great product. Actually saved us from an overheated tire that probably would have blown had we not been alerted and then stopped to let cool down.

  • Troubleshooting TST Sensor Won't Connect
    Hi Robert; do you have a TST system like the # TST-507-RV-4-C? How old are the sensors? The # TST-507-RV-S4 sensors have a battery life of 12-18 months so it sounds like it might be time to replace the sensor if it is no longer detected. They are also sold in pairs # TST-507-RV-S2. If it is an actual internal sensor like # TST-507-INT-S1 the battery life can last up to 4 years depending on use so it is less likely that the battery gave out unless it is old compared to the other sensors....

  • How to Install the Brass Tire Sensors for TST TPMS Systems
    On the Brass Tire Sensors for TST TPMS part # TST-507-RV-S2 there is a straight forward way to install them. I have included a video for you to check out on it. The short form is that the brass nuts go on the valve stem, the small o ring goes in the sensor, the sensor is screwed on to the stem and then when tight the brass nuts are backed up until they make contact with the sensor acting like a jam nut preventing removal. This can be accomplished using the provided wrench. The larger o...

    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.

You can mix and match the sensor types without issue so there will be no problem at all with this setup.
