If your car is equipped with tire pressure monitoring, you may wish to verify it yourself. Next time you drive, pay attention to the changes in tire pressure. You will find that even on a hot day, from cold to driving for a long time, the tire pressure is also There will be no significant changes.
Studies have also proved that when the tire temperature changes by 50 degrees Celsius, the change in tire pressure is only 0.5bar, and the safety tire pressure value of our car is generally 2.2bar-2.8bar, so as long as we follow the standard tire on the door frame Press to operate, the change of 0.5bar will not allow it to exceed the safe value at all.
The temperature of the tire will increase after driving for a period of time. At this time, the temperature of the tire is higher than the ambient temperature, so the influence of the ambient temperature on the tire pressure is negligible. In other words, the tire pressure in the hot tire state will not be affected by the seasonal ambient temperature. That is, the tire pressure in the working state will not be affected by the seasonal ambient temperature.
However, it should be noted that the problem of tire temperature is undoubtedly the fatal weakness for long-distance bus drivers and large truck drivers. Long-distance driving will accelerate tire wear, while excessively high temperature will accelerate tire rubber aging and steel wire softening. Overheating will directly feed back to the tread surface, which is the pattern. The pattern will accelerate the wear, but a good tire has a strong heat dissipation capacity. Therefore, the quality of the tire rubber can be tested at high temperatures, and the material of the pattern is rubber.
