What Causes the Car Tire Pressure Warning to Keep Going Off?
1 Answers
There are typically four scenarios when the car tire pressure warning keeps activating: 1. The tire pressure monitoring light comes on due to a punctured tire. This usually involves a very slow leak, making it difficult to immediately identify which tire is affected. In such cases, use a tire pressure gauge to measure the pressure (2.3 bar for front tires, 2.5 bar for rear tires). If the pressure is low, refill it and then monitor the warning light. If it lights up again after a few days, the tire may need to be removed for inspection. 2. Sometimes the tire pressure monitoring light activates due to overinflation. Standard tires: 2.4-2.5 bar; reinforced tires: 2.8-2.9 bar; maximum pressure: should not exceed 3.5 bar. Thus, if any tire exceeds 3.0 bar, it can trigger the warning light. 3. The warning light may come on due to prolonged driving with low tire pressure. If a tire's pressure is too low, high-speed driving can raise the tire temperature, increasing the pressure. In such cases, stop and rest or replace the tire with a spare immediately. 4. The warning light may activate due to long-term underinflation. When the pressure drops below 1.8 bar, the monitoring light will turn on. Therefore, regular checks should be performed to ensure the tire pressure monitor is functioning correctly.
