TW303 Truck TPMS System – Wireless Tire Pressure Monitoring System for Heavy Duty Vehicles
TW303 Truck TPMS System of sensor, repeater and receiver to detect the air pressure and temperature in the tire in real time. After collecting the pressure and temperature data in the tire, the sensor is sent to the repeater in the form of radio frequency, which is then sent by the repeater to the receiver, received and processed by the receiver and displayed on the display screen. When the pressure or temperature in the tire is higher or lower than the preset alarm threshold, the receiver will automatically complete the corresponding alarm to alert the user to the state of the tire. Through the operation of this system, it can improve the comfort of the vehicle, prevent tire burst, reduce fuel consumption, reduce tire wear and indirectly improve the power performance.

Product Advantages
Truck TPMS (Tire Pressure Monitoring System) is a smart tire safety management system designed specifically for trucks, trailers, buses, and heavy-duty commercial vehicles. By monitoring tire pressure and temperature in real time, it helps drivers and fleet managers reduce the risk of tire failure while enhancing transport safety and operational efficiency.
Real-time tire pressure monitoring
Truck TPMS monitors the pressure of each tire in real time and provides timely alerts to the driver, helping to prevent safety incidents—such as blowouts or loss of vehicle control—caused by abnormal tire pressure.
Reduce blowout risk
Helps drivers detect potential issues in advance, effectively reducing the likelihood of tire blowouts.
Extend tire lifespan
Truck TPMS helps maintain tires in optimal condition, thereby extending tire life, reducing the frequency of tire replacements, and lowering operating costs.
Save fuel
Insufficient tire pressure increases rolling resistance, causing the engine to consume more fuel. Maintaining proper pressure over the long term can significantly reduce fuel costs.
Multi-tire management
When used with a signal repeater, stable data transmission is maintained even for large trailers.
Smart fleet management
Real-time data monitoring enables proactive scheduling of tire maintenance, enhances transport safety management, and reduces manual inspection costs.
Suitable for Vehicle Service and Aftermarket Supply
This product is suitable for distributors, tire repair workshops, auto service centers and automotive aftermarket suppliers that need stable wheel balancing products in regular box packing.

TW303 Truck TPMS System replace
01Disassemble the old sensor valve assembly
Separate the old sensor and valve, clean the rust and old sealing ring residue in the wheel hub valve installation hole.
02Install a brand new sensor
Fix the tire pressure sensor buckle on the valve base, confirm that the air passage is completely aligned without gaps, and adjust the sensor angle to avoid rubbing against the tire wall.
03Dynamic Balance+TPMS Matching Reset
Perform tire dynamic balancing on the wheel hub and install balance weights to eliminate shaking.
Tip: The replacement of the sensor must be synchronized with the replacement of the matching valve sealing ring to avoid slow air release in the later stage; The metal valve should not be tightened with excessive force on the nut, as the sliding wire will directly scrap the wheel hub mounting hole.
Controlled details from production to finished product packaging
01Incoming Component Inspection
100% inspection for sensor circuit boards, aluminum valve stems, FKM seals and batteries. Valve stem diameter, base clearance and threads are gauged to avoid assembly jams or tilting.
02Assembly & Full Performance Testing
Complete air tightness test under simulated tire pressure to eliminate air leakage. 433MHz RF signal and ID code verification removes units with weak signals or invalid codes.
03Appearance & Structural Durability Check
Double-check thread and seal assembly for misalignment, missing seals or loose clips. Defective items are scrapped; qualified ones proceed to packaging.
04Finished Product Sorting & Standard Packaging
Sort single or 4-piece sets, verify part number 5Q0907275B and vehicle labels. Packaging inspection records are kept for full batch traceability.

Frequently Asked Questions
What vehicles are compatible with TW303 TPMS?
TW303 is designed for trucks, buses, trailers, RVs, and other heavy-duty commercial vehicles.
Does TW303 require removing the tire during installation?
No. The external sensors can be installed directly on the tire valves without removing tires.
What does the TW303 TPMS monitor?
The system monitors tire pressure and tire temperature in real time and provides warning alerts when abnormal conditions occur.
Why is a signal repeater needed for trucks?
Large trucks and trailers have longer distances between tires and the cabin. The signal repeater improves communication stability between sensors and the display.
