Hello everyone, I'm Xiao Li. A puncture is actually a very dangerous thing, because when we usually drive at low speeds, unless you are punctured by something, you are not prone to punctures even if you have expired tires for four or five years. Once the tire bursts, if it is handled well, it may just crash the car, and if it is not handled properly, it will be a tragedy of car destruction and death. Therefore, in the process of using the car, we must understand the various causes of puncture in advance and eliminate the hidden danger of puncture.
To be honest, there are many reasons why cars are prone to punctures, but the root cause of a good tire is that the tire is overheated, which I only learned after driving for 12 years when I chatted with a driver who has been driving a truck for a long time. Whether it is a car or a large truck, normal tires generally do not burst so easily, even if you run on the highway for three days and three nights without rest. However, tires often have some abnormal conditions in the process of use, such as tire pressure becomes low and cannot be detected in time, then the tire may overheat and cause a puncture.
Although today's cars have the function of tire pressure monitoring, many people are afraid that the tire pressure is too high and easy to burst during driving, so they specially beat the tire pressure to the critical point where the tire pressure monitoring system does not alarm, and feel that it is more comfortable and safer to drive. In this way, in the process of using the car, there are often warning lights with low tire pressure, and they have been numb, seeing the tire pressure alarm, according to their own experience, they feel that the tire has at least 1.9 tire pressure, and then they can be inflated when they are free, but it is often this mentality that sometimes there is an emergency to drive on the highway, and it is lucky that the problem is not big, and eventually the accident occurs.
What people don't know is that tire pressure that is too low is more likely to puncture. In the previous car did not have the mandatory standard tire pressure monitoring function, many people basically did not check the tire pressure, and it was difficult to see whether the tire pressure was low to the critical point by the naked eye, so there were more tire puncture accidents when running at high speed.
In fact, the tires are good under normal circumstances, and the water will not leak under normal circumstances, and only if there is a problem, it will leak, causing the tire pressure alarm. After the tire pressure alarm, it proves that the tire pressure is too low, and it may have been leaking, and now there may be 1.9 tire pressure, and the speed is too fast in the process of running at high speed, and the broken movement may soon become 1.5. Although it is relatively low, it can continue to drive, but at this time, the tire pressure is too low, which will increase the friction between the tread and the ground in the process of driving, resulting in abnormal force on the tire wall, and the temperature rise is more serious, and the tire will burst when the critical point is exceeded. This is also the reason for the high incidence of tire puncture accidents in the summer race, the temperature of the road surface is relatively high in summer, and the tires are abnormally heated during driving, and a combination of factors causes accidents.
Large trucks have the function of tyre drenching, I didn't understand why I kept drenching tires, but later I learned that large trucks are heavier than the cargo, and the tires are very stressed, which can easily cause the tires to overheat and burst. Spraying the tires with water is to assist in cooling the tires, especially in the process of braking, the friction between the tires and the ground will cause the tires to smoke, if they cannot be cooled down in time, it will cause the tires to be peeled off layer by layer and eventually burst the tires. I'm sure many people have seen the rubber peeled off the tires of large trucks on the road on the highway, which is caused by the overheating of the tires and the failure to cool down in time during the braking process.
In addition, tires with serious aging are also very prone to punctures, and the tire walls of this kind of tires have lost their elasticity and cannot withstand the force of the tires during high-speed driving, and eventually they will burst tires. Some tires with trauma are also very easy to puncture, trauma will cause the tire to become thinner, the thickness of the tire design can normally withstand the pressure at a speed of 120 kilometers per hour, but after a certain part becomes thinner, the critical point of the puncture in this part will become smaller, you may not be able to withstand the speed of 110 for a period of time, and eventually burst the tire.
Therefore, in the process of using the car, the prevention of punctures mainly starts from 3 aspects, the first pay attention to the change of tire pressure, the tire pressure should not be too high and not too low, the industry has a sentence to share with you: tire pressure 2.5 walking as steady as a tiger, tire pressure 3.0 walking fast and fuel-efficient, tire pressure 3.5 is not a crash is a Land Rover, tire pressure 4.0 lying down have to make up. Second, pay attention to the degree of aging of the tire, check it frequently after 5 years of use, and it is best not to replace the tire after more than 7 years. Third, pay attention to check whether the tires have external injuries, and it is recommended to replace the tires with trauma as soon as possible. If you do these 3 points well, you will basically not have an inexplicable puncture.
