Is a tire pressure of 270 normal for the Mercedes-Benz C260L?
1 Answers
The tire pressure of 270 for the Mercedes-Benz C260L is not normal. According to the international GBT2978-2008 standard, the standard tire pressure ranges from 2.4 to 2.5 bar. In winter, the tire pressure should be adjusted slightly higher by about 0.2 bar based on the standard tire pressure. In summer, the tire pressure can generally be about 0.1 bar lower than the standard to prevent blowouts due to high temperatures. Tire pressure reset method: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the completion of the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The system will alert when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, it can also cause the tire pressure warning light to turn on. For sensor damage, the only solution is to replace it with a new component.
