Which is Better: External or Internal Tire Pressure Monitoring?
1 Answers
Tire pressure monitoring systems, whether external or internal, do not have a definitive superiority; the choice primarily depends on the car owner's needs. Below is a brief introduction to tire pressure monitoring: 1. External: The external sensor works by using a needle to open the valve core, allowing the sensor to measure the air pressure inside the tire. The sensor cleverly utilizes the thread of the dust cap for fixation on the valve. 2. Internal: Installed inside the tire, it replaces the original valve with a sensor-equipped valve. The exposed part is minimal and does not protrude beyond the wheel hub. However, installation is more complicated, and the cost is significantly higher than that of external sensors.
