Five types of explosive tires need to pay attention to daily care is very important

The importance of tires to cars is self-evident. However, in daily life, tire puncture accidents due to tire aging, excessive wear, abnormal tire pressure, tire trauma and other reasons have occurred frequently, ranging from vehicle scrapping to endangering the safety of drivers and passengers. According to incomplete statistics, 42% of traffic accidents on highways are caused by flat tires. The death rate of flat tires over 160 kilometers per hour is nearly 100%. The flat tire became the "number one killer" of highway accidents.

So what exactly caused the burst of car tires?

Mr. Luo, a senior engineer at a maintenance service station in Chengdu, said that there are many reasons for tire puncture in vehicles, mainly related to temperature, road conditions, tire pressure, tire usage and tire trauma, especially temperature, which induces "tire puncture." "The culprit". Therefore, May-October every year is a high incidence of "flat tires".

High temperatures cause a flat tire. When the car is running under high temperature conditions, due to the effect of thermal expansion and contraction, the tire is easily deformed, and the tensile strength will decrease. In addition, the tire will continue to heat during driving, but the heat dissipation is relatively slow, so the air pressure Increased, resulting in a flat tire body burst.

Abnormal tire pressure caused a flat tire. Abnormal tire pressure refers to insufficient tire pressure and excessive tire pressure. Abnormal tire pressure can cause problems such as local tire wear, reduced handling and comfort, and increased fuel consumption. When the tire pressure is insufficient, the tire sidewall is likely to bend and break and burst. If the tire pressure is too high, it will cause defects (such as damaged parts) of the tire to burst during high-speed driving.

Poor tire condition results in a flat tire. Excessive wear, aging, cracking and trauma of tires are also one of the reasons for flat tires. Like the block after long-term friction with the ground, the pattern gradually becomes shallower, and when it is worn out, the mark should be stopped immediately.

Bad road conditions caused a flat tire. Road conditions also have a great impact on tires. For example, uneven roads or roads with a lot of gravel. When the vehicle is driving, it is easy to roll to hard metals or other hard objects, which can also cause the car to burst.

Speeding results in a flat tire. The temperature in summer is high, and the road surface temperature is also high. Continuous driving and speeding are prone to puncture.

In order to reduce the occurrence of flat tire accidents, Luo Kaijun, a senior engineer who has been in the automotive repair industry for nearly 30 years, has published a set of "unique tricks" to deal with car flat tires that he has summarized over the years, and hopes to enable car friends benefit from it.

Trick points: daily maintenance

Always check the air pressure of the tire under cooling conditions, including the spare tire, and find that the air pressure is insufficient, and immediately find the cause of the air leak.

Always check the tires for damage, such as whether there are nails, cuts, and tires that are damaged should be repaired or replaced in time.

Avoid contact of tires with oils and chemicals.

Carry out four-wheel positioning inspections on the vehicle regularly. If poor positioning is found, it should be corrected in time, otherwise it will cause irregular tire wear.

In any case, do not exceed the reasonable speed required by driving conditions and traffic rules. When encountering obstacles such as stones and potholes in front of you, you should avoid or pass slowly.
