What Causes Low Tire Pressure?
2 Answers
Tire pressure may drop due to: damage to the car tire or slow air leakage caused by aging tires. Abnormal tire pressure can result from the following reasons: Abnormal tire pressure: Generally, the system will alert if the pressure is below 1.8 bar or exceeds 3.0 bar. In such cases, a tire inspection and pressure adjustment are necessary. Tire pressure monitoring system not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will continue to display the previous data, causing the tire pressure monitoring indicator light to illuminate. Simply resetting the tire pressure will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, it can trigger the tire pressure warning light. In case of sensor damage, the only solution is to replace it with a new component.
When I drive to and from work, I always pay attention to the condition of my tires. The most common reason for low tire pressure is punctures caused by nails or broken glass, which create small air leaks that slowly deflate the tire. Temperature changes also have a significant impact, especially in winter when cold air causes the tire to contract internally, naturally reducing pressure. If the valve is aged or loose, it can also leak air; sometimes, issues with the wheel rim interface can cause gaps and air leakage. I often remind myself to check tire pressure regularly using a simple tire pressure gauge, as low pressure increases fuel consumption and accelerates tire wear. Ignoring it for too long may lead to a blowout, which is particularly dangerous. Developing a habit of checking every two months or paying attention during seasonal changes helps detect issues early. Tire aging or small cracks are also potential factors, and proper maintenance can extend their lifespan.
