What is the general tire pressure for cars?
2 Answers
There are specified pressure values for car tires. The standard tire pressure for passenger cars is within the range of 2.3-2.5 bar, with a maximum not exceeding 3.0 bar and a minimum not below 2.1 bar. According to the regulations and requirements of the international standard GBT2978-2008, the tire pressures for different tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum air pressure should not exceed 3.5 bar. Normal tire pressure in winter: In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2 bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure for car tires is 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.
My car has been running for over eight years, and I've really gone through some ups and downs with tire pressure. The standard tire pressure for sedans usually ranges between 2.3 to 2.5 bar, but you should always check the manufacturer's sticker on the door frame, as it varies by model. In summer when it's hot, I usually inflate them to 2.4 bar, and in winter, I increase it to 2.5 bar since tire pressure drops with the temperature. If the pressure is too high, the ride gets really bumpy, and the center of the tire wears out faster. If it's too low, the tire edges wear down quickly, and fuel consumption goes up. I check the pressure every month with a mechanical gauge, especially before long trips—after all, tires are the only part of the car that touches the road, so safety isn't something to take lightly. Don’t forget the spare tire either; once when I had a flat, I found out my spare was only at 1.8 bar.
