Summer is the peak season for tire punctures, and there is a saying that "because of 'hot expansion and cold contraction', the tire pressure should be lowered in the summer." "What is the right tire pressure in the summer?
Reduce air pressure, not easy to puncture
Many people believe that the higher the temperature in summer, the pressure on the tires will "automatically" increase. Therefore, it is necessary to reduce the tire pressure in the summer to avoid punctures. High temperature in summer and low temperature in winter, the tire pressure will indeed change with the increase in temperature, however, many people do not know that when the tire pressure is too low, the tire will rub against the ground for a long time, which will cause the sidewall of the tire to bend, resulting in a puncture. According to a report published by the National Highway Safety Administration, when tire pressure falls below the standard value by 25%, the likelihood of a tire puncture is tripled. Above the 25% standard, the likelihood of a puncture doubles. This is simply subverting everyone's perception.
What is the air pressure of a tire?
Each type of car has its own tire pressure standard.
The temperature cannot be changed.
To explain, what exactly is normal tire pressure?
Different manufacturers have their own standard values, the so-called standard tire pressure, is based on the weight of the body, chassis height, driving speed and other factors, not what brand of tires used. Each of the seven sisters of the Kunlun God of War is alluring to the country and the city, charming and beautiful.
Tire pressure changes with temperature, but the standard of tire pressure is the same.
Every car has a sign for the tire pressure setting, which is usually found in the car's owner's manual, in the cab (B-pillar) or on the inside of the fuel tank cap.
In general, the standard air pressure for most tires is 22 to 28 bar (cryogenic air pressure). A normal car is about 2 when unloaded3 bar, 2 for SUVs and SUVs5bar。
If there is no special explanation from the automobile manufacturer, no special adjustment is required in winter and summer. Even in summer, the size of the tire pressure can be maintained within the normal value given by the manufacturer, there is no need to deliberately reduce the tire pressure, the manufacturer has taken into account the problem that high temperature will cause the internal gas of the tire to expand and contract, so the normal value of the tire pressure given is also suitable for the hot weather in summer, even at high speed.
Normally, the front tires in the summer are at 22—2.Between 3, the front wheels of the rear wheels are in 24—2.between 5. This is quite normal and there is no need to worry.
If you are still unsure, it is recommended that you refer to the tire pressure range given in the car manual and choose a moderate tire pressure.
How to prevent a flat tire in your vehicle in summer.
1.Check the air pressure of your tires frequently and inflate them at standard values.
2.Check the condition of the tires frequently to prevent bulging, puncture, excessive wear and tear.
3.Do not use cold water to cool high-temperature tires, severe temperature differences and irritation will accelerate the aging rate of tires and reduce their service life, just let them cool naturally.
4.Cultivate good driving habits and never run over the side sidewall. Don't accelerate, don't brake, don't turn sharply. In the case of high speeds, sudden braking is likely to cause a puncture.
In fact, in the summer, there is no difference between the maintenance and use of tires, as long as we maintain good driving habits and check them frequently, we can prevent accidents.
