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.
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.
Much better than screw on cap type sensors. We had the cap type previously and had two valve stem failures. No issues with these in the wheel sensors.
I wanted a 6 tire TPMS that took up minimal space on the dash/windshield. I didn't want one that mounts to the end of the valve stem so I had these installed while putting new tires on. This has worked well for me over 8000+ miles and counting. Gives me confidence in so I don't have to worry about tire conditions while driving. It occasionally takes a while to connect at the beginning of a drive but was never a big issue.
These are much more responsive than the external stem based TPMD systems. They allow checking and filling like a car tire system. The Only drawback is the vehicle has to be moving to check tire pressures so it can't be used for pre-trip tire pressure check.
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.
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.
Had these installed when I replaced all 6 tires. Tire installer complained a little on the fit but got them all installed. Installed on a 2017 thor class C. Took a round trip ride from Connecticut to Oregon and back via southern circle Texas,Arizona etc. system never skipped a beat. Worked perfectly the entire trip. Never lost communication. Did not install booster antenna as motorhome is only 24’ long. Checked the actual tire pressure vs digital readout a couple of times and it was right on. One down side is the graphic on the display doesn’t show the rear duallies , just a total count of tires. You have to remember which sensors are on what rear tires. Very good and reliable system and delivery was fast
One of two elbow fittings was smaller so I had to go and buy a nipple to install it makingbit a bit taller, so I had to just reverse the install, photos added
I have not yet installed the system and the sensors so I am in hopes that they will work as planned and advertised so far they look good to me.
Do you have a question about this TPMS Sensor?

This has already paid for itself. On a trip to Banff, Canada, the low pressure alarm sounded. Pressure in one of my dualies had ped to 50 psi. I topped it off and kept an eye on it. Turned out to be a slow leak. Without this monitor, I could have ended up with a flat and a blowout. I had my spare switched in next morning at a local tire shop, and had them put the sensor moved to that rim. Cost me only $40 instead of what might have been, at best a few hundred, and possibly a serious accident.
