Why does the alarm still go off when the tire pressure is sufficient?

[AryaRose]

Reasons why the tire pressure alarm goes off despite normal pressure: 1. Malfunction of the tire pressure monitor or receiver module: This is a relatively rare occurrence, as tire pressure monitors generally have good durability and their lifespan is typically comparable to that of the vehicle. However, signal interference can sometimes occur, potentially causing the tire pressure monitor to give false alarms. 2. The car quickly passes over uneven road surfaces: When this happens, the high-speed impact on the tires can cause a temporary increase in internal tire pressure, especially during summer driving when the thermal expansion and contraction of air can trigger the tire pressure alarm. 3. The tire is punctured, but the air leakage is too slight to be visible: Sometimes, a tire may be punctured or experience slow air leakage due to aging. These minor pressure fluctuations are usually undetectable to the naked eye, but the tire pressure monitoring system can detect them.
