It's very hot in summer. Is the high tire pressure due to the weather?

When the temperature is high in summer, the air in the tire expands and the tire pressure rises. 2. When the vehicle is running, the temperature is higher after the tire rubs against the ground, which makes the tire pressure higher. 3. High temperature in summer softens tire rubber, and temperature has a great influence on tire pressure. The principles of thermal expansion and contraction are well known. The tire pressure of 2.5kpa in summer and the temperature difference in winter are tens of degrees. Without any air leakage, the tire pressure will drop to about 2.0 kPa. My car.

The tire pressure in summer is higher than that in winter. Which do you think is easier to break, a bulging balloon or a deflated balloon? Therefore, it is generally recommended to deflate slightly in summer and not to let the tire burst. A flat tire is sometimes caused by high tire pressure and low temperature in winter. Due to the influence of thermal expansion and contraction, the tires in winter are lower than those in summer, and sometimes the tire pressure should be appropriately increased to ensure the normal running of the vehicle, so the probability of tire puncture in winter is lower than that in summer.

Actually, you don't have to care about the tire pressure. Because the effect of thermal expansion and cold contraction on your tire is at most 0.2 bar; ; Our normal tire pressure is 2.5bar. Even the cheapest tire has a safe tire pressure fluctuation of 0.5bar, so don't worry. Because the conventional tire pressure is 2.5~2.8, the front and rear wheels are slightly different, but the temperature difference has little effect on the gas volume and does not need to be adjusted. The problems of tires themselves, such as extended service and wear exceeding the limit value, account for the majority. A healthy tire can withstand a wide range of tire pressure. Even when driving at high speed in hot summer, the tire internal pressure reaches or even exceeds 3.0bar, which is safe.

Because when the tire is rolled up, the air in the tire will heat up rapidly, and the influence degree is far greater than the external temperature. Therefore, it can be said that in the case of daily car use, the phenomenon of thermal expansion and cold contraction has almost no direct impact on tire pressure in winter and summer.
