What Are Snow Chains for Cars?

In winter, a thick layer of ice and snow is often formed on the ground. The road adhesion coefficient is low, and it is very inconvenient for cars to drive on it. On the one hand, the driving ability is poor, and I can't go on the slope; On the other hand, the braking force is poor, the braking distance is greatly extended, and traffic accidents are easy to occur.

Therefore, many people will install anti-skid chains on their cars to improve the adhesion coefficient and the driving safety when driving on such roads. So what are snow chains? What kind does it have? What should I pay attention to when using snow chains?

What are snow chains for cars?

The automobile anti-skid chains are generally made of steel chains or rubber chains and installed on the wheels of the automobile. They have the function of improving the adhesion coefficient of the wheels and preventing the wheels from skidding on ice and snow roads.

Its principle is to concentrate the gravity of the vehicle on several points of the anti-skid chain, generate a large pressure, roll into the ice and snow layer and destroy it, to improve the adhesion coefficient, increase the friction force, make the wheels have sufficient driving force and braking force, avoid skidding, and increase the safety factor of the vehicle.

Differences between snow chains and snow tires

In fact, they are two products with different properties. The anti-skid chains are only for special road conditions and can only be used on ice and snow roads. The side effects are also relatively large, but the anti-skid effect is good;

The snow tire is also called winter tire, which is designed for ordinary tires to become hard, brittle and have lower adhesion in winter. Its feature is that the tread is softer, which can ensure good adhesion between the tire and the ground even in cold winter weather, and has a certain anti-skid ability. It can be used in all weather and all road conditions without any side effects.

We recommend replacing winter tires in winter. Under normal urban road conditions, you don't need to use snow chains even if there is ice; If you need to go to places where the road conditions are very bad, you'd better take the anti-skid chains. Their anti-skid effect is better.

Precautions for use of snow chains

• The anti-skid chains are divided into different sizes, which are suitable for different wheel hub sizes and tire widths. When purchasing, you should pay attention to selecting the anti-skid chains that match the wheel sizes;

• The anti-skid chain must be installed on the driving wheel and the tire pressure must be normal. It is not allowed to install the anti-skid chain on the wheel with low tire pressure. After installation, stop the vehicle for inspection and adjustment after driving about 20 meters to ensure that the anti-skid chain is closely fitted with the tire;

• After installing the anti-skid chain, the car should keep running at a low speed, generally not exceeding 40Km/h, and pay attention to avoid sudden acceleration or emergency braking as far as possible;

• Before encountering ice and snow roads, the car shall be equipped with anti-skid chains. When the car drives into a good road, the anti-skid chains shall be removed in time. When installing and removing the anti-skid chains, the car shall be parked in a safe area, and necessary traffic warning signs shall be set up;

• After some models use snow chains, the tire pressure monitoring device will work abnormally and the tire pressure warning lamp will be turned on. There is no need to worry about this. After the snow chains are removed, reset the tire pressure lamp.
