How Long Can You Drive with the Tire Pressure Warning Light On?
2 Answers
Tire pressure warning light on means you should not continue driving. It is recommended to reduce speed, control the steering wheel, and find a safe place for inspection. Abnormal tire pressure can be caused by the following reasons: Abnormal tire pressure: Generally, the warning light will activate if the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring system not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will still record the previous data, causing the tire pressure warning light to illuminate. Simply reset the tire pressure monitoring system to 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 will also turn on. For sensor damage, the only solution is to replace it with a new component.
Last time when I was driving on the highway, the tire pressure warning light suddenly came on, which really made me nervous. I immediately pulled over to check and found the right rear tire completely flat. The mechanic said that with such rapid air loss, you absolutely must not keep driving—the tire sidewall could get crushed by the rim, or even suddenly blow out. If it's a slow leak with the pressure only about 0.3 bar low and the dashboard shows a yellow warning light, you can carefully drive 3-5 kilometers to find a repair shop. But remember, never go on the highway! I always keep an air pump in my car—when the yellow light comes on, I just top up the air to make it to the repair shop. Safety first—tire problems are much more dangerous than engine failures.
