The flat tire is the culprit of many car accidents, according to incomplete statistics, 42% of highway accidents are caused by flat tires, and if the speed is over 160m/h, the death rate is close to 100%. The tire puncture on highway has become the "number one killer" of highway traffic accidents. Among them, the driver's failure to respond in time after the tire puncture is the root cause of the tire puncture becoming a traffic accident tragedy.
1) The tire pressure is too low and it causes flat tire
Some drivers tend to lower the standard when inflating because of fear of "flat tires" in summer. In fact, this approach is very wrong. Because if the tire pressure is too low, the friction between the tread and the ground increases, and the rolling resistance rises, causing the temperature of the carcass to rise sharply, the rubber of the tread becomes soft, and the aging speed is accelerated, causing partial delamination of the carcass and increased tread wear. In this case, it is very likely that a flat tire will occur. When inflating the tires, if you do not know if the tire pressure is suitable, you can use the tire pressure monitoring system (also called TPMS) to help you determine.
2) The tire pressure is too high and it causes flat tire
Some drivers prefer to exceed the standard air pressure of the tire when inflating. However, it is known that this accelerates the wear rate of the tire, thereby increasing the possibility of a flat tire. Because if the tire pressure is too high, the tension of the carcass cord is increased, which accelerates the fatigue process of the cord, especially when it is over-inflated and overloaded, the internal stress of the cord is increased, the tire temperature rises rapidly, and the rubber aging speed up, causing a flat tire. Here, the TPMS system also can be used, or you can used the tire pressure monitor and tire pressure sensor.
3) The tire installation is wrong and it causes flat tire
A. The wheels are unbalanced. Some drivers directly use the spare tire without performing a dynamic balance test when changing the tire. If replaced with unbalanced wheels, especially during high-speed driving of more than 100 km / h, the wear caused by the imbalance is very violent, which eventually leads to a flat tire.
B. Improper positioning of the front wheels. The front wheel of the car is used for steering. Once the front wheel has a flat tire, the car will lose its ability to turn and cause serious traffic accidents. Some drivers do not accurately locate the camber angle and toe of the wheel when replacing the front tire, so that it is easy to cause a flat tire when driving.
4) Tires lack necessary maintenance and it causes flat tire
Some drivers have forgotten the regular maintenance of the car and do not change or maintain the tires, so that the tires will wear unevenly, and it is easy to form weak spots, which will lead to flat tires. In addition, if the stones trapped in the tire pattern are not removed in time, the wear rate of the tire will be accelerated, resulting in a flat tire.
If the tire suddenly burst during driving, don't be panic, as long as you hold the steering wheel with both hands, you can still control the car. While paying attention to the vehicles behind, brake slowly and drive away from the main road. Do not brake in an emergency after a tire is punctured, as this may cause the vehicle to flick or roll over due to uneven braking force.
If the rear tire bursts, the rear of the car will sway and bump. As long as the driver stays calm and grips the steering wheel with both hands, the car can usually be kept straight. In addition, it is best to step on the brake pedal repeatedly, so that the center of gravity of the car can be moved forward, so that the intact front tire is stressed, and the pressure on the tire after the burst is reduced. Remember, don't press the brake pedal too hard.
If the front tire bursts, it will seriously affect the driver's control of the steering wheel. In such a situation, the brake pedal should be pressed as lightly as possible to avoid the front part from being subjected to too much pressure and even causing the tires to break away from the rim. It is also necessary to hold the steering wheel firmly with both hands, so that when the car is driving to the left or right, it can be corrected immediately.
Now more and more cars are equipped with tire monitor system, which can make us drive more safely.
