What is the tire pressure for a car?
1 Answers
The tire pressure of a car is generally between 2.3-2.8 BAR, and as long as it is within this range, it is considered safe. Hazards of abnormal tire pressure: When the tire pressure is too low, tire wear accelerates, increasing the risk of a blowout and raising fuel consumption. When the tire pressure is too high, tire grip decreases and wear accelerates, while braking performance weakens. If the tire pressure is unbalanced across all four tires, the car may pull to one side, and the lifespan of the underinflated tires will be reduced more quickly. Precautions for measuring tire pressure: The tire pressure of cold tires and hot tires differs, so special attention is needed during measurement. Generally, hot tires have a pressure about 0.2 bar higher than cold tires. The standard tire pressure usually refers to the cold tire pressure. If measuring hot tire pressure, subtracting 0.2 bar gives the corresponding cold tire pressure value. Adjust tire pressure according to the season: Tire pressure should be adjusted appropriately based on the season. Due to the significant temperature difference between winter and summer, gases expand with heat and contract with cold. Winter tire pressure should be slightly higher than in summer. Generally, in winter, adjust the tire pressure 0.2 bar higher than the standard tire pressure. In summer, adjust to the lower limit of the standard tire pressure to prevent blowouts due to high temperatures.
