What Does It Mean When the Tire Light Comes On?
1 Answers
The reasons for the tire light coming on include a punctured tire or excessive tire pressure. Below is a detailed analysis of the specific situations: 1. Punctured Tire: This situation usually involves a very slow leak, making it difficult to immediately identify which tire is affected. In this case, you can use a tire pressure gauge to measure the pressure—2.3 bar for the front tires and 2.5 bar for the rear tires. If the pressure is low, refill it and then observe the tire pressure warning light. If it comes on again after a few days, you may need to remove the tire for inspection. 2. Excessive Tire Pressure: According to the international GBT-2978-2008 standard, the inflation pressure for passenger car tires should meet the requirements—standard tires should be between 2.4-2.5 bar, and reinforced tires between 2.8-2.9 bar. The maximum pressure should not exceed 3.5 bar. Therefore, if any tire exceeds 3.0 bar, it may trigger the tire pressure monitoring light. 3. Prolonged Driving with Low Tire Pressure: This situation usually occurs when one tire has significantly low pressure, causing the tire temperature to rise due to high-speed operation, which in turn increases the tire pressure. In such cases, you should stop and rest or replace the tire with a spare one promptly.
