Tuson TPMS lets you monitor your trailer or motorized RV tire pressure and temperature for increased safety and efficiency while traveling. Includes 4 monitoring sensors. Interchangeable valve stems fit 0.453" or 0.625" diameter holes.


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.


Delivered on time. have not put inside wheels yet. Will let you know when all the snow melts.

  • Will the Tuson Towable Tire Pressure Monitoring System Interfere with Factory TPMS
    The Tuson Towable Tire Pressure Monitoring System part # 335TPMS4WIVS will not interfere with factory installed TPMS.

  • Operating Distance of Tuson RV and Trailer TPMS # 335TPMS4WIVS
    I sent your question to Tuson about the Tuson RV and Trailer TPMS # 335TPMS4WIVS and they sent me the following with the attached picture: Based on our test results in an open space environment (without considering the shielding effect of vehicle structure), the max. distance between the sensor (installed in the tire) and the repeater is 20m (65.6 ft.), the max distance between repeater and receiver is 40 m (131.2 ft.). When considering a real-life situation where the shielding effect...

  • What Is Battery Life of Tuson Towable Tire Pressure Monitoring System # 335TPMS4WIVS
    The batteries in the sensors of the Tuson Towable Tire Pressure Monitoring System # 335TPMS4WIVS that you mentioned will last around 5 years with normal use and are not replaceable. You'd have to replace the sensor with the part # 335TPMS-SENS which comes with the battery.

  • Adding Sensors a Tuson TPMS System
    I reached out to my contact at Tuson who said that it has to be a Tuson sensor, like what you find in the Kit # 335TPMS4WIVS you referenced, to work with their system. No other programmable TPMS sensors can be used with their system so if you are needing more sensors you will need parts # 335TPMS-SENS and # 335TPMS-IVS for this specific system. If you have a different system please let me know what the part number is and I can let you know what parts you need.

  • Can Aftermarket TPMS Tools Be Used To Pair the Tuson TMPS Sensors
    I spoke with Tuson about the Tuson Towable Tire Pressure Monitoring System part # 335TPMS4WIVS and they stated they do not condone the use of aftermarket TMPS tools to program their sensors. That said, the system comes pre-programmed but if you had to replace one of the sensors or they were not installed in the correct locations then you can use the Tuson TPMS Display Power Cable part # 335TPMS-DPCABLE which will allow you to pair the senors without having the vehicle close-by otherwise,...

  • Does Tuson RV TPMS System Work Better on Steel or Aluminum Wheels
    The Tuson RV and Trailer TPMS System # 335TPMS4WIVS that you referenced will work equally well on steel or aluminum wheels. I verified this with my contact at Tuson RV. He said that the valve stems use a rubber grommet to seal to the valve stem hole so the valve stem itself doesn't even make contact with the wheel. Because of this the wheel's construction has no impact on the sensors for this system. I have attached a short video review and the complete installation manual that you...

  • Availability of Tire Monitor System for a 5th Wheel Trailer
    We do have a variety of tire monitor systems! If you can let me know how many axles your trailer has and what size wheels you have I can make a recommendation from the linked product list page. For example, the Tuson # 335TPMS4WIVS comes with 4 transmitters with interchangeable valve stems for varying diameter holes.

  • Dexstar Conventional Steel Wheel # AM20514 Valve Stem Hole Diameter For TPMS Sensors
    The Dexstar Conventional Steel Wheel # AM20514 has a 0.45" valve stem hole. Rather than using a TPMS that uses valve stem mounted sensors like the Tuson Towable Tire Pressure Monitoring System # 335TPMS4WIVS I recommend looking at sensors that will strap to the inside of the wheel like the TST TPMS # TST34FR. These sensors have the advantage of being able to mount deep inside the wheel center where they are better protected but will also not overly distort the wheel balance.

  • Valve Stem Dimension and Tire Pressure Monitoring System Compatibility
    The Aluminum Viking Series Valkyrie Trailer Wheel - 16" x 6-1/2" - 8 on 6-1/2 - Gunmetal Gray # AX02665865HDGMML utilizes the standard valve stem like the Americana Metal, Bolt-In Valve Stem - 1-1/4" Long # AM20906. These are the same diameter (7.7mm with threads 0.794 mm pitch) as you find on car and bicycle tires. It comes with the valve included so I don't know if the hole is 0.453" or 0.625" as both are standard options for that same traditional Schrader valve. Tire pressure...

  • Tire Pressure Monitoring System That can be Submerged in Water on Boat Trailer
    The TireMinder RV Tire Pressure Monitoring System # TM-A1A-6 is weatherproof which means it can withstand the elements, but should not be fully submerged in water. I contacted a representative of Tuson who said their Towable Tire Pressure Monitoring Systems can be submerged in salt water because like you said, they are mounted inside your trailer tires. The correct monitoring system with 6 sensors will depend on the size of your valve stems. You will need part # TPMS6WIVS which works...
