Watch the video on programing. It's so much easier. So happy I got this system. I hadn't checked my tire pressure in over a year. 15 pounds low on all tires. Not any more. So much safer now.

Very well however you must replace the valve stems with metal ones or they will crack and leak.

Great peace of mind now while towing my 29' travel trailer. Wish I had purchased it sooner. I have had mt share of flat tires on my travel trailer with two of them I did not even realize I had a flat and my tire shredded and had to buy a new tire. One of them even damaged the tire in front of it but I did not see anything until that tire went flat on the same trip.
So glad I will be alerted right away and likely save a tire from being destroyed or save me from possibly having an accident with the inability to stop properly if my tire was flat. Again, great peace of mind! I truly recommend this product 100%.


Love the TPM’s One problem was the contriful forse of the wheels made the units hit against the tire rims,, solved by installing metal valve stems. I covld have been told that

Good saved me twice, hit curb, bail in tire

Blow out, alarms went off, saved me from damage to TT, only now the tire sensor does not work, other three OK.

I forget I have it, which is the goal I think. The battery life on this thing is great. We travel 2-3 times per month, so I get a few months of life before I need to charge the head unit. The signal mostly worked before I hooked up the repeater it comes with. With the repeater in the battery bay, the tires sync up quickly.


Works great. The downside is we have to remove the sensors to check add/remove air. Wish we would have ordered the regular sensors

Which kit did you purchase? This particular kit does include sensors that are flow-through.

In use for almost1 year. Very happy with performance. Peace of mind is what this product provides me. Highly recommend!


Easy to install, easy to use and seems reliable so far.


Would buy again and would recommend to others. Product was easy to install but programming can be frustrating. Display works great and is easy to see. Repeater antenna was absolutely necessary and with it no dropped readings. Metal valve stems are required.


After owning it for a year, TST TPMS = POM (Peace of mind)


Customer service was really great. I am very happy with the product that I had received.


Pretty good product. Setup was a little cumbersome but I got through it with the included directions. It is meant for an tractor trailer with many axles so that is annoying that you have to cycle through all the extra tire locations during setup but in the end it works well.


The tire monitor seems good. The directions were not very well organized and left as many questions as instructions. The monitor connected easily and seems to stay connected in my short time of using so far. Caution: I did not realize when I bought this that rigid metal tire stems are required. Rubber ones are not stiff enough to support the weight of the monitor. I had to spend an additional $80 to replace the rubber stems with metal.


On a trip a couple of years ago, we had a blow-out on one of the tires on the travel trailer. I have towed trailers for 40+ years, both cargo and travel trailers and I have always been able to detect when something was amiss. This time, however I was shocked when I had no idea that a tire blew until I was flagged down by a passing motorist. It was just luck that the trailer itself was not damaged. I decided to purchase a TPMS.

The system installed easily. The repeater transmitted the data without problem to the in-cab receiver. The rechargeable in cab receiver did not require recharging except at the end of a three week trip and even then there was plenty left.

I did have some problem understanding the instructions on how to program the unit, specifically, deleting un-needed axles as this unit is made with 18 wheelers in .Once I got the hang of it, things went smoothly. I will come back to report any issues, but for now it's a 5 star for performance. No deduction for my problems on programming.


These work very well. I placed the little monitor on top of the dash to easily check the numbers. One time we were in very cold temps and the pressures were down below the limit I had set--boy howdy, the alarm works well!
Would I buy these again?? Yep.
Thanks etrailer


Works as expected. No issues. Would definitely recommend.


Excellent customer service!


Easy to set up! Works very well providing constant updates!

The service was great and the product arrived without issues. Thank you.
