Where is the tire pressure monitoring sensor located?

Tire pressure monitoring systems are divided into direct tire pressure monitoring systems and indirect tire pressure monitoring systems, with their installation locations differing as follows: 1. Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data is displayed. When the tire pressure is too low or there is a leak, the system will automatically issue an alert. 2. Indirect tire pressure monitoring: The working principle of indirect tire pressure monitoring is that when the pressure of a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in its rotation speed being faster than that of the other wheels. By comparing the differences in rotation speed between tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor the air pressure.
