With the cold weather, many parts of the north of the motherland will continue to usher in snow, the northern car owners have gradually replaced the car tires for winter tires, because this driving safer. According to the experiment, the summer tire ice braking distance of up to 8 times the trunk road. Why the winter tires in the north of the winter driving more secure, it is from the characteristics of winter tires.
Winter tires and summer and four seasons tires difference is that winter tires are specially designed for ice and snow climate, suitable for use in snow and ice pavement. Winter tires with a special rubber formula and pattern design, in the winter frozen, slippery and snow on the road, can provide better braking and handling performance. However, in Guangdong, Guangxi and other southern regions, the winter is almost no snow (the northern part of Guangdong mountain occasionally snow), so less use of winter tires.
Because each brand of winter tires using different materials are different formulations, interpretation of winter tires in the material, pattern design and other aspects of the characteristics
1. Soft rubber formula
Winter tires are made of softer materials than summer tires, which are primarily concerned with the effects of temperature. Because the summer tires in the low temperature conditions, the rubber will become hard, greatly reduce the grip of the tire, affecting traffic safety. The winter tires with a special soft rubber formula, even if the ice and snow pavement, the tires still maintain a soft texture, resulting in greater friction than the summer tires, so that vehicles in the snow and ice on the road, but also to maintain a greater friction, Thus ensuring the handling and safety of the vehicle.
2. Slit pattern design
Winter tires and summer tires In addition to the material, the pattern design is also very different, we can observe the tread surface pattern can identify winter tires to slit pattern-based, and slit pattern of the main role is to increase the ground area, Thereby increasing the grip on the snow and ice pavement.
3. deeper groove design
In addition to a lot of trench groove, the winter tire groove is also designed so deep, so the tire drainage better, but also increase the snow, is conducive to strengthening the snow capacity, the formation of snow column, to provide a strong driving force.
4. Greater ground area
Unlike the round tires of the round tires, the tires of the winter tires are square, and the ground area is larger in the same size, and the slippage can be prevented to a certain extent.
The difference between winter tires and summer tires
It is easier to wear
As the winter tires are softer and relatively weary in summer tires, it is recommended to replace the summer tires or the four seasons tires, except for the use of snow and ice in winter. In other climatic conditions, no problem. In addition, the snow tread pattern depth is less than half of the initial depth when the snow performance will decline, should not continue to be used as winter tires.
2. When to change the snow tires?
In general, 7 ℃ below to replace the winter tires. 7 ℃ is the summer tire rubber hardness changes in the critical temperature, the temperature below the summer tires rubber will harden, resulting in decreased grip, thereby reducing the driving ability and safety.
Winter tire use precautions
1. Due to the low temperature in winter, tire valve easy to aging lead to less noticeable leaks, must be frequent check air pressure to prevent tire fre
2. In general, more than four years (starting from the production cycle) of the winter tires, with the aging of rubber, its winter performance will decline, the need for timely replacement to ensure the safety of driving.
3. Winter tires are so soft and prone to irregular wear, and when the tread produces irregular wear, the pattern grounding area is reduced, will reduce the tire in the snow on the road surface grip, so on time to tire transposition.
4. When not in use, the winter tires are best assembled on the hub, and filled with gas, properly stored, and regularly check the tire pressure, until the next year when necessary to install the car.
