What are the causes of tire pressure warning?
2 Answers
The causes of tire pressure warning are: 1. The pressure of the four tires is too high or too low; 2. The tire is under-inflated due to slow air leakage or punctures caused by nails; 3. The ground temperature is too high; 4. The friction between the tire and the ground, as well as frequent braking, causes the brake pads to overheat; 5. The sensor gives a false alarm. Each car's matched tires have corresponding tire pressure, which directly affects the performance and response of the tires and, to some extent, influences fuel consumption. Excessive tire pressure will cause the middle of the tire to contact the ground in a convex form, significantly reducing the vehicle's grip on the ground, and it will not be able to provide sufficient friction during emergency braking. Insufficient tire pressure will cause the outer edges of the tire to contact the ground, preventing the entire tread from touching the ground, which fails to provide enough grip area. Moreover, frequent wear on the thinnest part of the tire sidewall will directly lead to premature tire failure.
When I first started driving, I often encountered tire pressure warnings, mainly due to tire leaks. Once on the highway, the alarm kept going off, and after pulling over, I found a puncture on the tire sidewall. Slow leaks are common, caused by things like nails or aging valve stems. Faulty sensors can also trigger false alarms—high summer temperatures can cause pressure to expand to the limit and trigger warnings, while winter cold can cause pressure to drop too low. Driving long-term on unbalanced tires leads to uneven wear and increased fuel consumption. A reminder to everyone: if the alarm goes off, pull over safely and use a manual tire pressure gauge to check—don’t risk driving too long. Safety first—checking tire pressure monthly can prevent most issues. When replacing tires, remember to recalibrate the sensors to avoid false alarms. In short, don’t ignore warnings; get repairs promptly for peace of mind.
