Is a tire pressure of 260 normal for the Buick GL8?
1 Answers
The tire pressure is relatively high. It is generally recommended to maintain tire pressure between 2.3 and 2.5 for optimal comfort and safety. In winter, the tire pressure should be adjusted slightly higher by about 0.2 bar based on the standard tire pressure of the vehicle. In summer, the lower limit of the standard tire pressure is usually 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 prevent 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 if 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 wheel 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 monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also included. Compared to using only a direct system, 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 for all four tires' actual pressures like a direct system.
