What are the indicators of unstable tire pressure?
2 Answers
If the tire pressure is unstable, the tire pressure monitoring warning light on the dashboard will illuminate. The indicator is a yellow symbol—an irregular circle without a seal, with four small spikes at the bottom and an exclamation mark inside. The tire pressure monitoring light indicates abnormal tire pressure. Generally, there are three main reasons for abnormal tire pressure: Abnormal Tire Pressure: Typically, the system will alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, a tire inspection and pressure adjustment are required. Tire Pressure Monitoring Not Reset: After inflating the tires, if the tire pressure is not reset promptly, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged Tire Pressure Sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, the tire pressure warning light may also turn on. In case of sensor damage, the only solution is to replace it with a new component.
As an experienced driver who's handled many cars, I'd say the most obvious sign of unstable tire pressure is when that yellow exclamation mark light pops up on the dashboard - shaped like a tire with an exclamation point inside, warning you to check immediately. The steering becomes noticeably heavier when driving, as if the wheel is fighting against you, especially during turns where handling feels particularly sluggish with reduced maneuverability. The car body vibrates intensely too, with amplified bumpiness at highway speeds - even small pebbles make the car shudder noticeably. The increased tire contact area causes fuel consumption to spike. Once during a long trip, I encountered severe sidewall wear with small cracks developing on the underinflated tire - a truly alarming sight. The greatest danger lies in potential blowouts during extended high-speed driving. I strongly recommend installing a tire pressure monitoring system for real-time readings, plus checking and refilling to standard levels during every maintenance check. Never compromise on safety when it comes to tire pressure.
