What does it mean when abnormal tire pressure is detected?
2 Answers
Tire pressure monitoring showing an abnormality indicates that the air pressure in the four tires is outside the normal range. Here is relevant information: 1. Tire pressure: Tire pressure is essentially the blood pressure of a car, and it plays a crucial role in the vehicle's performance and power. When tire pressure is abnormal, the monitoring system does not prevent the car from being driven. Therefore, before each trip, the owner should perform a static check to ensure the tire pressure matches the specified value. If it does not, do not drive the vehicle. 2. Handling method: If abnormal tire pressure is detected while driving, immediately check the tire pressure. If the low-pressure warning light comes on, avoid sudden steering or emergency braking. While reducing speed, move the vehicle to the roadside and stop as soon as possible. Driving with low tire pressure can cause permanent damage to the tires and increase the likelihood of tire failure.
The tire pressure warning on the highway last time really scared me, so I quickly pulled over to the emergency lane to check. This alert usually falls into several scenarios: The most likely cause is a slow leak from a nail puncture—in my case, a screw was embedded in the sidewall. A sudden drop in tire pressure during cold weather often triggers the alarm too; I remember the light came on right after starting up last winter at -10°C. Leaky valve stems due to aging are also common, especially in older cars with brittle rubber parts. Wheel rim deformation or sensor malfunctions can cause false alarms—a friend’s BMW once had a false alert after the rim got dented. Long-term underinflation is even riskier, as overheated sidewalls may lead to a blowout. If the warning lights up, avoid sharp steering, turn on hazard lights, slow down, and use a tire pressure gauge to check actual values. Cold tire pressure should match the reference number on the door frame label.
