in the hot summer, the most likely thing for a car running at high speed on the road is a flat tire. How to prevent a flat tire in summer? Once a flat tire is a great threat to life, it must be on guard for the car owners. What should we do when the car blows out in summer?
1. Check the tire sidewall regularly for cracks
If there is a problem with the sidewall of the tyre, it must be replaced in time. Even if there are only small cracks in the sidewall, it is necessary to repair or replace the tire in time, because these small cracks are likely to cause air leakage or even tire blowout.
2. Rotate the tires regularly
Tire transposition is to make the four tires on the car wear evenly. Generally, it is better to change the tire position once when driving about 10000 km. And the price of tire transposition is not expensive. Generally, the labor cost is about 100 yuan. It's OK to change by yourself, if it's not too much trouble.
3. Check tire condition regularly
Generally speaking, the tread pattern thickness shall be at least greater than 1.6 mm. If the tread often passes through a slippery road, it is recommended that the tread pattern thickness be greater than 3.2 mm. How to judge the thickness of the pattern? It's very simple. A dollar coin can do it. Insert the tread groove along the top of the national emblem. If you can see the entire national emblem, it means that the tread thickness is insufficient. It's time to change the tire.
4. Always pay attention to bulges and blisters on tires
In case of bulge or blister, don't hesitate to change it.
What about a flat tire?
First, confirm whether the front tire or the rear tire is flat?
Front tire burst:
Do not touch the steering wheel with both hands. Make sure to hold the steering wheel tightly and adjust the direction of the car. Do not move too much or too hard. In addition, it is not allowed to step on the brake suddenly. After the vehicle speed gradually reduces, drive the vehicle into the emergency lane, and then place a warning triangle at a distance (100-200m) behind the vehicle.
Rear wheel blowout:
The car will move to the side of the flat tire. At this time, the receivable valve will slow down the car's speed. It is worth mentioning that, unlike the front tire blowout, because the rear wheel does not have the guiding function, and the later bearing weight of the general car is relatively low, so the rear tire blowout is not very dangerous, just need to hold the steering wheel.
Tire blowout
First of all, let's talk about the flat tire, especially when walking at high speed. Every year, 46% of highway accidents are caused by tire failure, and tire blowout accounts for 70% of the total accidents. Once the speed reaches 160km / h, the death rate of drivers and passengers is close to 100%.
Because of the high temperature in summer, it is easy to cause tire pressure to be too high and tire thermal deformation to blow out. The hidden danger of running at high speed is further increased. So, what do we need to know about a summer blowout?
1. Check the tires for damage, bulges or inserts. The aging of tire materials is easy to cause bulging and cracking, while the complexity of the road surface will increase the risk of binding nails and embedding stones. Therefore, we should form the habit of taking out a few minutes to check the tires.
2. In summer, do not pour cold water on the tire to cool down. Rapid cooling is easy to crack the tire. Let the tire cool down naturally.
3. When driving, pay attention to avoid potholes. Severe collision will not only damage the tires, but also cause problems with the wheels.
4. Tire pressure is an important factor of tire blowout, so tire pressure monitor can be added. In summer, the tire pressure can be reduced properly, but it must not exceed 10% to cause tire deformation.
5. One last thing about nitrogen. First of all, nitrogen is really useful, especially for long-term high-speed car owners. If you just run downtown at ordinary times, no more than 80km / h, you don't need to worry about nitrogen.
Spontaneous combustion
If your car is more than 5 years old, you need to pay attention to the spontaneous combustion. Although some good quality cars have been used for more than ten years, but now the automobile industry is developing too fast, there are too many brands, and the quality is uneven. The low-end models should pay particular attention to the problem of checking the aging of components, and also pay attention to the cultivation of good driving habits at ordinary times.
1. Aging of lines and oil lines is easy to cause fire, so when the car reaches a certain age, you should consciously check more. Also, do not change the oil circuit and circuit at will. If the technician is inexperienced, it is easy to leave a potential safety hazard.
2. Pay attention to the problem of engine fouling, and eliminate the possibility of high temperature ignition on the engine surface.
3, the flammable goods in the car should be handled well, especially the two common and flammable goods, perfume and lighter. If there's a lens or something that focuses light on these inflammables, it's not unusual to have a fire.
