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.

Note: To inflate or deflate a tire you must remove the sensor.
Great customer service. I was given their name and a direct line in case I had other questions. Impressive.
Fast shipping / product works great.
Tpms is great stuff. Use it on my motorhome and towed vehicle.

Have used TST in the past and needed extra sensors for the new coach.....etrailer provided their normal fast service!

Worked great on my 2nd trailer
After ordering this product, delivery was very fast. Installation and matching the sensors to my existing unit was easy. All worked well.
Arrived just in time, thanks for the fast shipping
Super fast shipping! Ordered 4pm on a Tue and they arrived Wed morning!
Easy to install and easy to pair and they seem to work. I paired them with TST series touch screen 770-D which I had. I haven’t used them on a road trip yet.
misleading on when delivery was going to take place and passed on other options that would have gotten me the product earlier, which I needed, but wasn't able to do.
These work great with my 507 head unit. Arrived a day early.
Quick delivery and excellent product!
Haven’t used them yet but it was definitely the best price.
Received sensors and had them paired in less than 10 minutes to my TST 770 display. Pre-order discussions with Bryce D @ etrailer regarding compatibility to the TST 770 display eliminated any questions I had. Great support.
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.

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.
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.
Easy to install, sync right up, no issu es.
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.
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!
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..
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
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.
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.
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
