What is the normal tire pressure for a Mercedes-Benz?

[LeKing]

According to the requirements and regulations of the international GBT2978-2008 standard, the tire pressure for Mercedes-Benz vehicles is: 2.2-2.5 bar. In winter, the tire pressure should be adjusted slightly higher than the standard tire pressure by about 0.2 bar. In summer, the lower limit of the standard tire pressure is generally sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. There are three commonly used methods for tire pressure monitoring: Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect tire pressure monitoring: When the pressure in a tire decreases, the weight of the vehicle causes the rolling radius of that tire to become smaller, making it rotate faster than the other wheels. By comparing the differences in rotation speed between the tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) introduction: It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a 4-wheel indirect system is also equipped. Compared to using only direct systems, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system can. system.
