Why do you need a TPMS system for your trailer tires? Maintaining properly inflated tires has been proven to:

  • Increase Fuel Economy
  • Extend Tire Life
  • Improves towing safety by giving the trailer better steering, stopping and traction
  • Increases Environmental Efficiency

Help prevent tire blow-outs by constantly monitoring tire pressure and temperature wirelessly with Tuson Towable Tire Pressure Monitoring System.

The Tuson Towable Tire Pressure Monitoring System (TPMS4W) instantly detects trailer tire pressure and temperature of 3-vehicle memories for up to ten (10) tires per vehicle memory. The wireless tire pressure and temperature sensors mount inside your trailer tires using the interchangeable valve stem (IVS) and transmit signals in RF mode to a monitoring module inside your tow vehicle that displays individual tire pressure and temperature. The Towable TPMS allows drivers to monitor the current status of all their trailer tires, increasing towing safety by allowing the driver to monitor all tires while towing.


This model contains interchangeable valve stems. When dismounting the tire, check to see which grommet fits in the wheel's valve stem hole to assemble the correct grommet on each valve stem. Generally, the smaller .453 size is compatible with trailer tires 16 inches in diameter or less. The larger .625 valve stems are for tires larger than 16 inches, which would be found on extra-large trailers. 

Internal Sensor

The internal sensor monitors tire pressure and temperature in real-time and wirelessly transmits data to the receiver. The sensor is attached to the valve stem inside the tire to prevent damage or theft. Internal sensors provide the most accurate and reliable pressure and temperature readings and are more environmentally-friendly with longer-lasting battery life than external sensors.

 External VS Internal TPMS Sensors

Interchangeable Valve Stems (IVS)

Not sure what size your current valve stems are on your wheels? No worries! Tuson now makes retrofitting your tires with our TPMS system easier than ever with the interchangeable valve stems (IVS). The IVS is designed to be universally compatible with the 0.453” and 0.625” diameter rim hole sizes in passenger vehicles, towables, and fifth wheels. Our IVS is currently made out of brass (aluminum version will be available soon). With the rubber or nickel-plated steel washer and rubber grommet you can rest assured that galvanic corrosion will not occur.

RF Repeater

The RF Repeater is motion-activated and designed to boost the signal strength from the tire sensors to the receiver (monitor) in the tow vehicle.  The waterproof repeater is a plug and play device using power and ground wires to connect to the trailer battery or any constant 12/24V power source for easy installation. When powered to the trailer battery, the repeater transmits trailer battery voltage to the receiver.


The receiver (monitor) allows the driver to monitor the tire pressure and temperature of up to 10-wheels for up to 3-vehicle memory selection. The receiver will also monitor trailer and vehicle battery voltage. The receiver has two modes: driving and setting mode. Driving mode cycles between pressure, temperature, and trailer battery for the selected vehicle memory. Setting mode allows drivers to fully customize their trailer tire monitoring system.

Continuously Monitors Critical Tire Monitoring Parameters

  • Tire Pressure
  • Tire Temperature
  • Sensors' Battery Voltage
  • Repeater's Input Voltage

Visual and Audible Alarms

Tuson TPMS Feature Icons

When the TPMS sensor detects any abnormalities, the sensor immediately transmits visual and audible alarm warnings to the receiver. Never miss a beep!

Easy Installation & Pairing

Each Tuson Towable TPMS kit comes with designated wheel orientation marks on the surface of each sensor. When each sensor is installed according to the corresponding wheels, no initial pairing is required. Our design makes installation and pairing easy.

Long-term Cost Savings

Using the Tuson Towable TPMS not only saves you money through increased fuel economy, extended tire life, but the internal sensor has up to 5x the life expectancy of an external cap sensor. Tuson's internal sensors use the same integrated sensor design used in the OEM automotive industry and can last up to 10 years, depending on the frequency of use.

Adjustable & Customizable Settings

Customize your trailer tire monitoring settings just the way you like it right at your fingertips. The Tuson Towable TPMS receiver allows you to select the pressure (kPa, psi, Bar) and temperature (°C, °F) units and set your desired temperature and pressure value to suit your needs.

Interchangeable Wheel Order

No need to remove the TPMS sensor from each tire during a tire rotation. The TPMS receiver allows you to easily change the locations of the sensors according to the tire rotation arrangement.

Nice Quality System

Purchased this tpms to install on an older motorhome that did not have factory tire monitoring. In addition to the included power cable I hardwired the receiver to accessory power and mounted it to the dash for a factory look. The system works flawlessly!
I would highly recommend it to anyone looking for a high quality system.

Thank you for your favorable review. We are glad TPMS works well for you.

Works As Advertised

My case was a bit rough. However customer service came through for me, on a Sunday no less. This system works. And is much better than other valve stem mounted cap style monitors. I am very impressed with what it does. This gave me piece of mind over the 1000 miles I've pulled my travel trailer thus far this year. You'll be glad you bought it.

We are glad our Tire Pressure Monitoring System performs up to your expectations. we try hard to make sure you are pleased.

Solid system

Wanted to add a TPMS system to our camper, as I've heard too many scary stories about how much damage a blowout can do, and I wanted to know what was going on "back there" on the trailer. I knew I wanted an internal mount automotive-type sensor, and was impressed with the idea of the battery saving feature on the Tuson internal sensors. I was going to mount the repeater with a switch so that I could disconnect power when the trailer was to be parked for a long time, but then read the specs to see that the repeater also goes into "sleep" mode on it's own to save power drain on the trailer battery.
We haven't had the system on a long trip since installation, but on a test run the system started indicating within 50 feet of movement, and seemed to work great on that short trip. Looking forward to the confidence the data will provide on longer trips.

Thank you for your review. We are glad TPMS4W works well for you.

Great Monitoring System - Update

We have now used our Tuson TPMS on several trips including one over 4,000 miles. We love the system and it has given me a piece of mind that I had not had while towing our large 5th wheel. The only issue we have experienced is when the repeater came loose from the ceiling of my RV "basement," but even then it continued to work as it was supposed to. I simply reattached it and all is fine. The tire sensors are very accurate and the monitor rotates thru the pressure, temperature, and battery charge slow enough for me to check but fast enough that if something went wrong we'd know quickly.

I would highly recommend this monitoring system; particularly over any of those that are attached to the valve stem on the outside of the tire - these are much more dependable.

We are happy the system you purchased performed well for you. We are grateful for the kind words.

I have not been able to give this system a full workout so can only pass on an initial impression with install and a short road trip. The high quality of the manufacturing is obvious on the first examination.
The engineers are very helpful and easy to access. I have a new Denali dually with a trailer tow package and discovered the OEM TPMS from GMC will not work with G rated tires or others rated above 80 psi. Does GM think that you buy a truck like that to haul small trailers?
The package arrived promptly with all components and fairly understandable directions. Pulled all four tires and had the GMC dealer install the sensors as they said they would when we discovered GMC’s sensors would not fit. With a short trip around Tampa Bay I found the system worked well. I was surprised how warm the tires got with such a short trip. I mounted the receiver down on the console near the power source and the signal relay inside the forward hatch on the trailer.
One of the major advantages will be how easy it is resetting the tire location after rotation. Good product if you need such a solution. I am currently installing their brake actuator as I found mine had gone south with the short trip around the Bay. Manufacture quality and helpful engineering access applies to my experience with the actuator, also. So far that is as I’m not finished.

Thank you very much for the favorable review. We are glad you were satisfied with the purchasing experience and the assistance from our engineers. We strive to provide you with the best possible service and products.
