What is the normal value for car tire pressure?
2 Answers
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 stipulations and requirements of the international GBT2978-2008 standard, the tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum tire 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.
I've been driving for 20 years. The normal tire pressure for cars is usually between 32 to 35 PSI, but it depends on your specific vehicle model. Generally, the label on the door frame or the user manual will indicate the correct pressure. If the tire pressure is too low, it increases fuel consumption, causes severe wear on the tire edges, and may even lead to a blowout in summer. On the other hand, if the pressure is too high, the center of the tire wears out faster, making turns less stable and compromising safety. I recommend checking the tire pressure once a month with a tire pressure gauge. The easiest way is to use the self-service equipment at gas stations for inflation, and the most accurate measurement is when the car is cold. Seasons also affect tire pressure—in winter, the pressure naturally drops due to lower temperatures, so you may need to add more air. In summer, overheating can cause the pressure to rise, increasing the risk of leaks, so be careful not to exceed the limit. Maintaining the right tire pressure makes driving safer and more worry-free.
