Alcoa wheel rims are not compatible with TPMS4W-A. Wheel valve hole is too small. Use Ball Type Sensors or Steel Band Type Sensors instead.
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-A) can 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 aluminum interchangeable valve stem (IVS-A) 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 aluminum 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.
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 aluminum interchangeable valve stems (IVS-A). The IVS-A 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-A is currently made out of aluminum (brass and steel band kit versions are available). 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.
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
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.
