Why does the tire pressure monitoring light on the Bora keep coming on?

[DeWilliam]

The frequent illumination of the tire pressure monitoring light on the Bora is a very dangerous signal, indicating abnormal tire pressure that requires immediate attention. Tires are a primary condition for vehicle safety. The principles of automotive tire pressure monitoring are 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. Wireless transmitters send the pressure information from inside the tire to a central receiver module, which displays the tire pressure data. When the tire pressure is too low or there is a leak, the system automatically alerts. 2. Indirect tire pressure monitoring: Indirect tire pressure monitoring works by detecting when a tire's pressure decreases, causing the vehicle's weight to reduce the rolling radius of that tire, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, it monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of tires to monitor pressure.
