Why do wheels have to be chained in winter in most parts of northern China?

Snow chains play a certain role, so it is necessary to install snow chains. They are generally used in road ice and snow conditions. Anti-skid chain is generally made of steel chain or rubber chain, which has a certain anti-skid effect. The snow chains used in different models and environments are different. For large and heavy trucks, iron snow chains are more suitable. Iron snow chains have high durability and low price, but the main disadvantage is that they will damage tires and the ground. In winter, there is water on the road surface, which is easy to form ice and snow, and the road surface is slippery, causing cars to slip and causing safety accidents. If there is a snow chain, the car will increase the friction of the tire and increase the braking to ensure the safety of the original car. Here is a detailed introduction to the types of snow chains and the precautions for use.

I. Types

1, the rubber chain is easy to install and beautiful, with little damage to the tire hub. However, the shortcomings are also obvious. After all, it is made of rubber. Long-term use needs to be removed, and it wears quickly.

2. The other is an iron snow chain. Because it is made of chain, it has long service life and good anti-slip effect. But the disadvantage is that the installation is very troublesome and the tires are very worn! In addition, the installation of snow chains will affect the handling of the whole vehicle, especially when passing through potholes.

Second, matters needing attention

1, it is better to install snow chains before driving, rather than after encountering icy roads, because installing snow chains in temporary parking lots is more troublesome than installing them in advance, which is not conducive to safety. Park the vehicle in a safe area before installation and disassembly. If you are on a busy road, you need to set up the necessary traffic warning signs.

2. Don't install snow chains when the tire leaks.

3. The size of snow chains is also limited, which is suitable for different wheel hub sizes and tire widths. Pay attention to choose the snow chains that match the wheel size.

4. After installing the snow chains, the driving speed shall not exceed 40km/h, and attention shall be paid to avoid sudden acceleration or deceleration.

5. When the vehicle enters the road without snow chains, please remove the snow chains in time. After installation, don't start too fast. Observe the reaction of the tire after adapting to the protective chain. If there is abnormal noise or deviation, it should be adjusted in time.

6. During driving, if there is no snow on the road ahead, it is best to remove the snow chain to avoid wearing four tires and prolong the service life.

7. Even with snow chains, drive carefully, especially on icy roads, and control the speed at any time to ensure safety!

8. If the tire collides or wears after installing the snow chain for many times, it is best not to feel that there is a problem and replace it directly.

9. Improper selection of snow chains is not only unsafe, but also increases potential safety hazards. Especially rubber snow chains, it is best to check them before use, especially in the case of severe cold and low temperature, which is easy to break.
