What Causes Frequent Tire Pressure Alarms?
2 Answers
The reasons for frequent tire pressure alarms are: 1. Tire replacement without resetting the tire pressure module; 2. Nail punctures causing tire pressure changes; 3. Tire inflation without resetting the tire pressure monitoring system; 4. Prolonged vehicle inactivity leading to tire pressure drop without inflation. Below are the functions of tire pressure monitoring: 1. Immediate alarm when rapid or slow air leakage occurs due to tire puncture. 2. Warning when tire loosening causes uneven friction, raising tire temperature to 70°C to prevent blowouts. 3. Alert when prolonged lack of inflation causes tire pressure to fall below the vehicle's set limit, preventing low-pressure-induced temperature rise and blowouts.
After driving for so many years, I often encounter tire pressure system alarms, usually caused by tire leaks or pressure imbalances. The most common issue is punctures from nails or sharp objects, leading to slow leaks through small holes, which trigger the system when the pressure drops below the warning threshold. Temperature changes also have a significant impact, especially in winter when cold air can cause a noticeable drop in tire pressure, frequently activating the warning light. Additionally, aging tire pressure monitoring sensors, depleted built-in batteries, or signal interference can cause false alarms, requiring timely replacement or calibration. It's a good habit to invest in a quality tire pressure gauge and check regularly, keeping the pressure within the recommended range on the door label. If alarms persist, don’t delay—visit a professional auto repair shop to identify the root cause, ensuring safe driving and avoiding the risk of a blowout. Regular attention to tire wear and maintenance can prevent most issues.
