What are the pros and cons of OBD tire pressure monitoring?

[BentleyLee]

obd tire pressure monitoring has the advantage of not requiring modifications to the vehicle's original wiring, as it utilizes the car's ABS data to determine tire status, eliminating the need for additional sensors or displays. Generally, once installed, it is maintenance-free and doesn't require battery replacement. Additionally, OBD tire pressure monitoring often includes features like fatigue driving alerts, automatic locking, and flashing lights. The downside of OBD tire pressure monitoring is the lack of precise numerical readings for tire pressure, and there's a delay in obtaining tire information through wheel rotation speed. In terms of monitoring method, OBD tire pressure monitoring is considered an indirect system. It reads the vehicle's ABS data via the OBD interface, monitors the rotation counts of all four wheels, performs high-speed calculations, and then determines whether each tire's pressure is normal. An alert is triggered when it detects that a tire's pressure is below the normal level.
