How to cool tire properly in summer
Four seas network: after entering three volts, the weather is getting hotter and hotter. In many areas, the temperature is more than 40 degrees, and the surface temperature is as high as 60 degrees. Many drivers are afraid that the tires will not be able to bear it. It's like pouring cold water on the tires to cool them. Who knows that it will be very dangerous.
Recently, there was a man who used cold water to cool the tire, but he didn't expect the tire to explode, so he was injured! How to cool the tire properly in summer? Let's see the details below!
On the 25th, a driver was watering the tire in the service area to cool down, and checking the tire pressure, when the tire suddenly exploded and injured him.
At about 1:30 p.m. the day before yesterday, there was a loud noise in the Jiangxia service area of the Beijing Hong Kong Macao expressway. Only one man fell beside a heavy semi-trailer and his face was bleeding. After receiving the alarm, Caidian brigade of provincial high police headquarters quickly sent police and medical staff for rescue.
The police learned that master Tian, the driver, drove a semi-trailer to run the freight and had a rest in Jiangxia service area at noon. When he was about to leave the service area, he was afraid of a flat tire due to the high temperature, so he carefully checked the tire. He took a bucket of cold water and poured it on the high-temperature tire to cool down, and then hit the tire with an iron bar to check the tire pressure. Unexpectedly, a tire exploded suddenly. His face, neck, arm and other injuries bled. Fortunately, the injury was not serious.
The high-speed traffic police remind drivers that the weather is hot in summer and the road temperature is too high. When checking the tires or glass of the vehicle, do not cool down abruptly. In case of any abnormality of the vehicle, please seek the help of professional personnel to prevent accidents due to improper operation.
Misunderstanding of cooling tire
Splash cold water, stimulate instant cooling?
When the urban temperature reaches above 30 ℃, the temperature of cement ground and asphalt road surface after heat absorption is beyond imagination, which can reach 50 ℃ or even above 60 ℃, and the inner part of the carcass is close to 100 ℃. Black rubber tire absorbs heat, and the friction between body gravity and road surface will cause tire burning. If a bucket of cold water is poured out suddenly, local thermal expansion and contraction will cause tire internal structure deformation, which is not only easy to cause tire blowout, but also common in some cases.
Release some air, reduce pressure and cool down?
Some car owners consider to deflate the tires directly. At this time, the temperature will not be reduced, but will continue to rise due to the decrease of air pressure and the increase of deformation. The temperature of the tires will rise higher and the service life of the tires will be reduced. If the tire pressure and temperature are too high, it is easy to cause tire blowout.
Solutions to tire cooling:
When driving in summer, always check the temperature and air pressure of tires, which can be lower than the normal air pressure. If it is found that the tire temperature or tire pressure is too high, you should immediately find a shade to rest, and continue driving after the tire temperature drops naturally and the tire pressure returns to normal. Do not damage the tires of the vehicle due to the temperature drop in the picture.
