Why does the car dashboard show abnormal tire pressure?

[Jessie]

The reasons why the car dashboard shows abnormal tire pressure are: 1. The tire pressure is not within the normal range; 2. The tire is leaking or punctured, causing insufficient air pressure; 3. The tire pressure is too high. Tire pressure refers to the air pressure inside the tire. The effects of excessive tire pressure are: 1. It affects the braking performance and driving comfort of the car; 2. Excessive tire pressure increases the friction between the tire and the ground, reducing tire adhesion; 3. It accelerates the wear of the central tread pattern, shortening the tire's service life. The effects of insufficient tire pressure are: 1. It accelerates rubber aging and increases tire wear; 2. It causes the tire body to expand, making it prone to cracks on both the inner and outer sides; 3. It increases the contact area between the tire and the ground, causing the tire to overheat.
