Hello, everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Tucson towable tire pressure monitoring system with the four ball sensors. Now this tire pressure monitoring system will allow you to monitor your trailer or motor home tire pressures and temperature. A properly inflated tire can increase fuel economy, extend tire life, and even improve safety and environmental efficiency. Now this kit here will include everything I have laid out here on the table. We'll start with the receiver monitor display.
Comes with the suction cup holder, the four ball sensors, the repeater, the 12 volt power cable that plugs into the monitor, some installation hardware and a nice user's manual to describe how this all its goes together and how it operates. Now we'll start with the monitor. This monitor can display and store three separate sets of 10 tire sensors, so 30 total for three separate trailers or RV configurations. You can easily change between the three settings when towing different trailers, and we do sell additional ball sensors that you can add to it if you need to add any sensors. Those are sold separately.
The sensors use radio frequency to transmit realtime data to the in-cab receiver. The motion activated ball sensors will install in the inside of the tire to prevent damage or theft. And the ball type sensors have a nice hard plastic body with a rubberized coating for durability. They do weigh less than one ounce, so they won't affect any tire balance. And the other nice thing is each sensor has a unique ID number to identify the sensor to the receiver.
If you look at the box when you get 'em, they'll be labeled. So when you initially install these, you put 'em in that position. And then when if you rotate your tires, the interchangeable wheel order means that there's no need to move the sensors after a tire rotation. All you have to do is put it into the monitor display of what it's located on the vehicle or trailer. Now these sensors have a longer life expectancy than external cap sensors.
These will last anywhere from five to 10 years depending on its use. Now the receiver will display critical tire monitoring parameters. It'll show you tire pressure monitoring range from zero to 203 PSI. It'll show you tire temperature monitoring range from a negative 40 degrees Fahrenheit to 257 degrees Fahrenheit. It'll also show you the sensor's battery voltage and the repeaters input voltage. Now it does offer visual and audible alarm warnings. They're immediately sent to the receiver when any problems are detected. The screen can be turned off while you're still monitoring in the background. And there's an alarm volume that can be adjusted or muted. It does offer customizable settings to allow you to adjust to your desired units of measurement. The temperature units, you can do either Fahrenheit or Celsius. And the pressure units, you can do either KPA, PSI, or BAR. The dimension on the monitor itself is a width of about 4 1/2 inches. A height of about 2 1/8 inches, and a depth of only about one inch. Now the radio frequency repeater here, this will enhance the radio frequency transmission range between the sensors and the receiver. Has a cable length of 90 inches. And the dimension on the repeater, it's gonna be about 2 1/2 inches by 3 1/2 inches by about 7/8 of an inch thick. And the operating voltage on this unit is 12 to 24 volts DC. But that should do it for the review on the Tucson towable tire pressure monitoring system with the four ball sensors.

Ratings & Reviews
This product has worked well and as intended. I like that it has its own display and so I don't need to use my phone screen. I wish that the trailer had come with these installed, but since it didn't, these are the best type of retrofit that you can get - mounted to the wheel on the internal side of the vale stem (same as the original equipment would have been). They are not cheap, but they have worked as they we designed and I would get them again. The peace of mind from having a functioning TPMS, especially with a tandem axle trailer, is really great and in my opinion, worthwhile.
I m more than pleased with the TPMS. We were riding on cheap Chinese-made tires that ended up with four of the six different sidewall failures. The internal TPMS alerted us to the building temperatures in the tires, and we were able to get them serviced before they blew out and caused untold damage to our RV. They do not stress the air valve stems like external sensors and give accurate readings. The downside is that I have to move the RV before the readings show up on the monitor in the cab. But that is a small price to pay for the peace of mind that they bring us on the road.
This is a true TPMS system for a trailer/RV or even your car.
Typical 'screw on' TPMS valves end up rusting onto your tire stems and are less precise. These Tuson TPMS go inside the wheel like a normal TPMS system and are more reliable and longer lasting.
The range is great and the display cycles between temperature and pressure, giving you ample time to react to bad bearings etc instead of finding out you have a problem when a tire blows up.
Installed in the summer of 2023 with new tires. Easy to install the relay unit at the front of the 5th wheel. The display is bright and easy to use. This tire pressure and temperature monitor and disk brakes I purchased from Trailer has removed the stress from wondering about the condition of the tires and brakes. This is much less cost than repairs to the trailer for a blowout as I can attest.
I tow a 29' travel trailer, and we just returned home from a 2-week trip where the Tuson TPMS system performed extremely well. This system replaced my previous TPMS system that had the sensors that screw on to the outside of the valve stems. I used to have to wait until I turned at a sharp enough angle for the dash mounted receiver to pick up the signal...not anymore!
Prior to our trip, I installed the repeater before the tire shop installed the sensors, and the receiver did not acknowledge the trailer battery voltage signal. I even moved the receiver to within a foot of the repeater, still no signal. After the four sensors were installed, everything worked perfectly. I even fudged on the repeater location (directions tell you to mount horizontally under the trailer tongue, I mounted vertically where there was a convenient pre-drilled hole) with no ill effects. The TPMS display cycles between tire pressure, tire temperature, and trailer battery voltage at reasonable intervals. I strongly recommend for ease of installation (thanks tire shop guys) and ease of use.
I purchased the Tuson TPMS system because I wanted an internal tire sensor, not a external stem cap type.
I bought the interchangable valve stems because I was going to get new rims for my trailer and didn't know what size would work.
The tire store ended up putting their own stems in because the rims I got were to thick for the Tuson stems.
The hardest part was figuring out there are physical buttons on the side of the receiver, not touch buttons on the screen.
I also installed the power to a fused switch for my electric hitch lift so I can turn off transmitter when parked.
I like the information the unit provides. Besides tire individual tire pressure, you also get temperature of sensor (which can indicate a low tire or hot wheel bearing), and voltage to transmitter unit (which lets me know if the trailer wiring is connected to pickup as voltage is higher when being charged by pickup).
System is expensive, but worth it because of the internal sensors and convenience.
Only complaint is it seems that sensors can't be cloned for replacement.
Would I buy again, yes. I have recommended this system to all my friends that have trailers.
The Tuson TPMS works well on our travel trailer. I had the sensors installed in the wheels when purchasing new tires, and installed the relay and wiring to the battery myself. As a mechanical engineer, I liked that this uses standard automotive type internal sensors, and I wanted to be able to get reliable internal temperature readings just as much as pressure, in order to keep an eye on the wheel bearings in addition to the tires. The system has worked flawlessly for a year now. I also like that the display in the cab can be turned "off" but still will alert you if out of limits, if the display itself is too distracting (it hasn't been). Very pleased with the system.
So far, the time that I he’s been using it and what everyone tell me about the sensor it working very good/well but the only thing I can’t program the to/on my 2020 Chev truck using the monitor on my dash of the truck
Works very well. I stalled this on a 2023 KZ Durango Gold 5th wheel that is 43' in length. Picked up all four times within seconds of moving and gave very accurate info throughout the entire trip (3.5 hours). This is an automotive-grade sensor kit and works very well. Installation is not hard. Just have to find a tire shop that will install the sensors for you. I was able to find one that did it for me at a very reasonable rate. I paid $10 per tire so $40 total for the installation. I would highly recommend this to anyone looking to install a TPMS system in their RV
Just had the sensors installed on the wheels of my 2018 MB Sprinter 3500, and the monitoring display recognized the sensors within about 300 feet of driving and one minute. Paid America's Tire in Walnut Creek $132 for the install ($22/tire including re-balancing), there was no need for "re-learning".
Great product.
I did a lot of research before committing to this one, it checked most of my boxes. If it holds up well and the sensor battery lasts as claimed, it will deserve a five star rating, but for its lacking a couple of features I think are important. I would like to suggest a couple of improvements, should the manufacturer wish to hear them:
1) Adding an integral battery and solar cell would be a huge improvement, I don't like having to plug it into the cigarette lighter, which stays powered up when I shut off the car, putting a drain on the battery unless I remember to shut off the monitor. Another significant advantage to adding this would be not having a cable draped from the front of the instrument panel up the middle of my windshield.
2) make the valve stems about 3/4" longer. I am dealing with duallies in the back, and the edges of MB wheels end up really close to the threaded portion of the valves, making it very difficult to attach the valve extenders.
3) Add a software "switch" to disable the trailer battery status display, this would be accessible through the setup menu. I have no need to monitor trailer battery status, but 1/3 of the display time is taken with a null display.
Bottom line up front: This system works but it doesn't.
After a year of use, these are good, but far from perfect. I find the pressure readings of them to be very accurate to my tire gauge. This past summer, I had the "experience" of losing a trailer wheel. It sheered all 6 studs and I lost the whole wheel (I went back and never did find it, thankfully etrailer had an exact replacement wheel!) I'm not quite sure how long I drove after it fell off, but I imagine it wasn't more than 10-15 minutes.
I was noticing the tire pressure and temperature starting to increase on the side that I had lost the wheel on - and that was my alarming factor. My 10,000lb GVWR bumper pull toy hauler with 4400lb axles would average about 120 degrees. On really hot days I would see it go up to 130 but not much more than that.
Cold tire pressure was 80 and they usually run at 85PSI or so on the road. I noticed the other wheel starting to climb to 90-92PSI and the temp going up to 135, and the other three were at the usual 120 degrees or so. Right about that same time, a trucker honked at me and I pulled over to see I had no wheel.
So now the million dollar question, right? How in the world did I lose the ENTIRE WHEEL, yet the system never alerted me that it wasn't reading info from the wheel I lost? GREAT QUESTION!!!
After I got the studs replaced, I'm back on the road. The system didn't turn red and start beeping at me until another 15 minutes of driving down the road - Obviously I did not have a TPMS sensor installed on my spare tire, so it should have alerted me that there was no reading detected right away.
Tuson had a lackluster response on this with something along the lines of "the TPMS sensor only sends an update once a minute to save battery life". Well that's fantastic, so why the heck didn't it start beeping at me a minute after I lost the wheel?
Looking forward to replacing my external TPMS sensors with the internal ones.
Great product. Only reason for a 4 rating is that the antenna cover keeps falling off and has done this so many times I ended up losing it . Connects great and definitely gives me piece of mind.
These CHANGED MY LIFE! I was so distressed constantly trying to check the pressure in my tires, especially my duallies, after my inner duallies both went flat in the middle of nowhere due to a leaky valve stem extender. These are metal and replace your regular valve stems, and then I added new valve stem extenders additionally and checked for leaks really good everywhere before reinstalling, and now, NO MORE PROBLEMS and I can monitor continuously. Hallelujah!!! I love that these monitor my pressure and temperature for each tire in real time and it works so well I didn’t even need to use the signal booster on my class C RV. Being on the road full-time is stressful enough and there’s always something to monitor/repair; getting these took one thing to worry about off my plate. If you’re on the fence, buy them now!
I'm very glad I bought this. While headed down the freeway I started hearing some very low beeping(not knowing there's adjustable volume on this unit, that has now been turned up). I stopped and noticed the right rear tire icon being red, and was able to use my portable compressor to make it home before doing tire damage.
Purchased 6 sensor Tuson ball tpms, 9v portable power and activation tool. The tool came in handy to verify pressure and location prior to reinstalling tires on motorhome. Display shows 6 sensors in 3 horizontal rows. Outside duals shown in 3rd row. Installed repeater in lower compartment of motorhome. Will be nice to not worry about theft of external sensors, air leaks or moisture getting in the external sensors. May add 4 more sensors to cover Jeep toad which brings total sensor count to max 10.
It works well and with the included signal repeater, it works with my 42 foot 5th wheel RV. Just need to understand that you get no tire readings or trailer voltage reading until you're rolling down the road for a few minutes. You can't see your tire pressures before starting your trip.
I trailer a classic car in an ATC 20ft enclosed trailer and wanted to monitor trailer tire pressures to avoid catastrophic tire failure. The install was straight forward,easily done with anyone with basic skills. I opted for the "ball type" sensors. The sensors work great. I also have 2 spares on board with sensors that activate about 50% of the time when there is enough trailer movement to trigger them into on mode. The only thing I would change would make the cigarette charger optional and offer a USB alternative.
Looks like a good system but. I did not see anywhere that the tire pressure sensors are not compatible with Alcoa wheels. Found out when the tire shop tried to install them but the included valve stems are too big in diameter to go through the Alcoa wheels. Ended up returning.
Really like to monitor pressures and temperatures in real time. When one of the tires started leaking I got warning right away before damage was done and was not dependent on other drivers to warn me about destroyed tire after the fact.
Since sensors are internal, I can trust the readings reflect tire/wheel temperature better than external stem sensors.
Internal sensors do not start reading until trailer moves but that is not a problem since readings appear within seconds once wheels start rotating
Great product! Installed on my 2 axle car trailer my dad built for me and that I have been using since the late 90's. Looking forward to purchasing another kit when I'm ready to put tires on my new 3 axle trailer.
The shipping carrier had a problem. eTrailer had a solution to fix it. Received my item today. Thanks eTrailer.
So Far Excellent. Still working flawlessly after 1 year. Screen is easy to read.
