Does the BMW 530 have tire pressure monitoring?

[McAlexis]

The BMW 530 has tire pressure monitoring, but it does not display real-time tire pressure values. It features a passive alarm function. 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 for each tire. The system will automatically alert when the tire pressure is too low or there is a leak. Indirect tire pressure monitoring: The working principle of indirect tire pressure monitoring is that when the air pressure of a tire decreases, the vehicle's weight will cause the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the system monitors the tire pressure. The indirect tire alarm system essentially relies on calculating the rolling radius of the tires to monitor air pressure.
