Why does the tire warning light come on but no problem is found upon inspection?

[AllisonDella]

If the tire pressure warning light on the car dashboard comes on, but no abnormalities are observed in the tires, the possible reasons are as follows: 1. Slow air leakage: The tire may be leaking air extremely slowly, making the leakage phenomenon almost imperceptible to the naked eye. Usually, when the warning light comes on, the driver will immediately check all four tires. If the phenomenon is not obvious, it may create an illusion for the driver. 2. System malfunction: The system may have a fault, causing a false alarm. The sensor or receiver module may be damaged, or the wiring may be faulty, leading to incorrect tire pressure detection. 3. Increased tire temperature: After prolonged driving, the temperature of the tires rises, and due to thermal expansion, the tire pressure also increases. Once the tires cool down naturally, the tire pressure warning may automatically disappear.
