What Causes the Car Tire Pressure Light to Illuminate?
1 Answers
The reasons for the car tire pressure light to illuminate are as follows: 1. Punctured tire: A slow leak caused by a puncture may trigger the tire pressure monitoring light, making it difficult to immediately identify which tire is affected. In this case, use a tire pressure gauge to measure the pressure (recommended: front 2.3, rear 2.5). If the pressure is low, inflate the tire and then monitor the warning light. If it illuminates again after a few days, a tire removal inspection may be necessary. 2. Overinflated tire: The tire pressure monitoring light may also illuminate due to excessive tire pressure. According to the international GBT2978-2008 standard, the recommended inflation pressures are: standard tires: 2.4-2.5 bar; reinforced tires: 2.8-2.9 bar; maximum pressure: should not exceed 3.5 bar. Therefore, if any tire exceeds 3.0 bar, the tire pressure monitoring light may activate. 3. Prolonged driving with low tire pressure: Extended driving with insufficient tire pressure can cause the tire temperature to rise during high-speed operation, leading to increased tire pressure and triggering the warning light. In such cases, it is advisable to stop and rest or replace the tire with a spare promptly.
