tirerightcarThe importance of it is self-evident.But in daily life, becausetireTire burst accidents caused by aging, excessive wear, abnormal tire pressure, and tire trauma have occurred frequently, ranging from scrapped vehicles to endangering the lives of drivers and passengers. According to incomplete statistics, 42% of highway traffic accidents are caused by flat tires, and the death rate of flat tires at speeds above 160 kilometers per hour is nearly 100%. A flat tire has become the "number one killer" of highway traffic accidents.
a Expert Secret
Five situations are prone to "puncture"
So what causes the burst of car tires? Luo Kaijun, a senior engineer at Chengdu Kelon Service Station, said that there are many reasons for vehicle puncture, which are mainly related to temperature, road conditions, tire pressure, tire usage and tire trauma, etc., especially temperature, but also induces "tyre puncture." "The culprit." Therefore, from May to October of each year is a high incidence of "flat tires".
1. The high temperature causes a "tyre burst". When a car is running under high temperature conditions, due to thermal expansion and contraction, the tires are prone to deformation, and the tensile strength will decrease. In addition, the tires continue to heat up during the driving process, but the heat dissipation is relatively slow, so the air pressure changes The increase of the carcass will result in a puncture due to the carcass being too thin.
2. Abnormal tire pressure causes "tire burst". Abnormal tire pressure refers to insufficient tire pressure and excessive tire pressure. Abnormal tire pressure can cause local tire wear, reduced handling and comfort, and increased fuel consumption. When the tire pressure is insufficient, the sidewall of the tire is likely to bend and break and burst. If the tire pressure is too high, the defects (such as damaged parts) of the tire will burst during high-speed driving.
3. Poor tire condition leads to "tyre burst". Excessive wear, aging, cracking and trauma of tires are also one of the causes of tire blowouts. After long-term friction between the pattern block and the ground, the pattern gradually becomes lighter. When it is worn to the replacement of the mark, stop using it immediately.
4. Bad road conditions lead to a puncture. Road conditions also have a great impact on tires. For example, on uneven or gravel roads, the vehicle is likely to be rolled onto hard metal or other hard objects during driving, which can also cause a tire to blow out.
5. Speeding leads to a puncture. In summer, the temperature is high and the road temperature is also high. Continuous driving and speeding are prone to puncture.
