What does it mean when the tire pressure warning light comes on?

The reasons for the tire pressure warning light coming on include: 1. A puncture causing the tire pressure monitoring light to illuminate; 2. Sometimes the tire pressure is too high; 3. Driving with low tire pressure for an extended period triggering the tire pressure monitoring light. It is recommended to visit a repair shop for diagnosis. The effects of excessively high tire pressure include: 1. Accelerated wear on the central tread pattern of the tire, reducing tire lifespan; 2. Causing steering wheel vibration or deviation, decreasing driving comfort. The consequences of excessively low tire pressure are: 1. Increased movement in various parts of the tire, leading to abnormal heat generation due to excessive rolling; 2. Increased friction coefficient with the road surface, resulting in higher fuel consumption.
A few days ago, I also encountered a situation where the tire pressure warning light came on. I was driving to the countryside for an outing, and the light turned on just as I got on the highway. I immediately slowed down and pulled over, noticing that the right rear tire was noticeably flat. There could be several reasons for this: the most common is a punctured tire leaking air, or a slow leak caused by an aging valve stem. Sometimes, a sudden drop in temperature can also lower tire pressure and trigger the alarm. That time, I used the portable air pump in my car to inflate the tire to the standard 2.5bar, but the light remained on. Later, I learned that I had to manually reset the system—by navigating the steering wheel menu to resolve it. I recommend everyone develop the habit of keeping a tire pressure gauge in the car and checking all four tires when refueling—better safe than sorry.
