What is the appropriate tire pressure for cars in summer?
2 Answers
In summer, the appropriate tire pressure for cars should be adjusted between 2.3bar and 2.5bar, with the exact value determined by the manufacturer's recommendation. Due to the principle of thermal expansion and contraction, summer tire pressure should be maintained at the lower limit of the standard tire pressure. If the car is parked under the sun in summer, the tire pressure should be reduced by an additional 0.1bar from the standard tire pressure to avoid tire blowouts caused by high temperatures. Tire pressure plays a significant role in the lifespan of the tires and driving safety, so it is essential to check the tire pressure regularly, especially before long-distance or high-speed driving, to ensure driving safety.
I've been driving for over twenty years, and there's really a knack to adjusting tire pressure in summer. The standard values marked on the car door frame or manual are measured when the tires are cold. In hot weather, I usually reduce this standard value by about 0.1 to 0.2 bar. For example, if the standard requires 2.5 bar, I'll inflate to 2.3 or 2.4. Why? Because when the car is running, the tire temperature rises, and the tire pressure naturally increases. Leaving some room like this is safer. If you really can't find the data, for ordinary cars in summer, inflating to the range of 2.2 to 2.4 bar is generally appropriate. It's best to adjust it in the early morning after the car has been parked overnight, when the temperature is closest to the measurement conditions. You should check with a tire pressure gauge every month, and if you find anything unusual, you can also check for bulges or cracks on the tires. After all, a tire blowout is no joke—it's about the safety of the whole family.
