How to handle flat tires during driving

The puncture is the biggest problem that threatens the safety of high-speed driving. If a puncture occurs above 160km/h, the death rate is almost 100%. However, you don’t have to worry too much. As long as we can drive at the speed limit, even if a puncture accident happens on the highway, it’s not a big deal, but don’t panic.

Here's how to deal with a puncture accident :

1. If you have found a tire leak while driving, you should hold the steering wheel tightly, slowly brake and decelerate, try your best to control the direction of travel, and leave the lane as quickly as possible. When leaving the main lane, emergency braking should not be used to avoid traffic accidents.

2. When the rear tire bursts, it should be kept calm, hold the steering wheel firmly with both hands, and strongly control the vehicle to keep a straight line and slow down and stop.

3. When you realize that the front tire has burst, hold the steering wheel firmly with both hands, loosen the accelerator pedal, and try to control the straight-line driving of the vehicle. When the front tire punctures, the danger is greater. We must try our best to control the steering wheel and quickly grab the low gear. When the front wheel burst has turned, do not over-correct. You should gently depress the brake pedal to slowly decelerate the vehicle while controlling the direction.

4. When a puncture occurs during driving, try to use the method of “snipping”, use the engine brake to slow down the vehicle slowly, and avoid frantic stepping on the brake pedal in order to prevent the vehicle from escaping and causing more dangerous situations.

5, the correct way to suddenly burst tires when driving is to maintain calm, slowly raise the accelerator pedal, grip the steering wheel, control the vehicle straight, until the vehicle speed is reduced, and then gently step on the brake pedal.

6, when the tire pressure is too low, high-speed tires will appear wave deformation, resulting in increased temperature and puncture.

7. The correct way to avoid a flat tire is to inspect the tires regularly, remove the foreign substances in the tire trenches in time, and replace the tires with cracks or deep injuries.

Mr. Luo, a senior engineer at a maintenance service station in Chengdu, said that there are many reasons for causing the vehicle to burst, mainly related to air temperature, road conditions, tire pressure, tire usage, and tire trauma. Especially the temperature, it is induced "flat tires. "The culprit." Therefore, the 5-10 months of each year is the peak period for punctures.

The main causes of car punctures in summer hot weather are :

High temperatures cause punctures. 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 is reduced. In addition, the tire continuously generates heat during driving, and the heat dissipation is relatively slow, and the air pressure is accordingly The increase in the height of the carcass resulted in a puncture of the carcass.

Abnormal tire pressure leads to puncture. Abnormal tire pressure refers to tire pressure and tire pressure is too high. 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 sidewall of the tire can easily bend and break and burst. The tire pressure is too high, it will make the tire defect (such as damage) in the high-speed driving process burst.

Poor tire conditions lead to flat tires. Excessive wear, aging, cracking, and trauma to the tires are also among the causes of puncture. As the block is rubbed against the ground for a long period of time, the pattern gradually becomes lighter and should be immediately stopped when worn and replaced.

Poor road conditions lead to flat tires. The impact of road conditions on the tires is also large, such as uneven roads or gravel roads, the vehicles are easily rolled into hard metal or other hard objects during driving, and can also cause car punctures.

Speeding leads to a puncture. Summer temperatures are high and the surface temperature is high. Continuous driving and speeding are prone to punctures.

In order to reduce the occurrence of puncture accidents, Luo Kaijun, a senior engineer who has been navigating for nearly 30 years in the automotive maintenance industry, has disclosed a set of “unique tricks” that he has summarized for many years to deal with car punctures, and hopes to enable riders to benefit from it.

How to prevent puncture in the car

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

Always inspect the tire for damage, such as nailing or cutting, and repair or replace the damaged tire.

Avoid tire contact with oils and chemicals.

Regularly carry out four-wheel alignment inspection on the vehicle. If it is found to be poorly positioned, correct it in time. Otherwise it will cause irregular wear of the tire.

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