What Are the Reasons for the Tire Pressure Indicator Light Staying On When the Tire Pressure Is Normal?

[DelJordan]

When the tire pressure is normal but the indicator light remains on, the possible reasons are: 1. The tire pressure was previously too low, and although it has been replenished, the tire pressure monitoring system has not been reset, retaining the original fault code. 2. The tire pressure sensor is damaged or there is a system malfunction. The hazards of low tire pressure include: 1. Shortening the lifespan of the tires. 2. Increasing the friction coefficient with the road surface. 3. Creating factors that are detrimental to driving safety, such as making the vehicle prone to veering off course. The hazards of high tire pressure include: 1. Reducing the tire's friction and adhesion, affecting braking performance. 2. Causing steering wheel vibration and veering, reducing driving comfort. 3. Accelerating localized wear of the tread pattern in the center of the tire, leading to a shorter tire lifespan. 4. Increasing vehicle vibration, which indirectly affects the lifespan of other components.
