【The owner's family car knowledge】As the saying goes: A journey of a thousand miles begins with a single step. The tire is the “foot” of a car. If a car wants to drive normally and safely, of course, it cannot do without the normal function of the tire. In many places, it is gradually entering the coldest time in winter. It is common for roads to freeze, which will cause driving inconvenience to car owners. The icy and snowy weather is not only a test of the driver's driving skills, but also a test of the car itself. How can you use and maintain the tires correctly so that your car can give full play to its advantages? Here are some tips for everyone.
Ensure inflation pressure
In winter, the temperature is low. According to the principle of thermal expansion and contraction, car owners in winter should appropriately increase tire inflation pressure to reduce tire wear and consumption. But at the same time, if the road is icy and slippery, the tire's high inflation pressure will affect the tire's grip. Under normal circumstances, in the cold winter, we recommend using an inflation pressure 10%-15% higher than the standard, but it cannot exceed the maximum inflation pressure specified in the product manual. In addition, in the cold winter, the car often checks the inflation pressure of the tires. When the inflation pressure of the tires is insufficient, it should be supp

In addition, in the cold winter, the car often checks the inflation pressure of the tires. When the inflation pressure of the tires is insufficient, it should be supplemented in time.
Control driving speed
In the cold winter, if it is restarted after parking, because the tires are relatively stiff, it must be driven at a lower speed for a period of time after starting to drive at normal speed. Of course, the most important thing for safe driving in winter is to control the driving speed. Especially when driving on the highway, you must pay attention to control the speed, do not accelerate or brake quickly, so as to ensure safety, and effectively protect your car and tires in the cold season, so as to avoid traffic accidents.
Strengthen protection and cleaning
Pay special attention to the cleanliness of tires before and after driving in the cold winter. Before driving, check whether the tire groove is covered by ice and snow, and if it is, clean it. If the ice trapped in the groove is hard, you can't pry and dig it forcibly, and you can't pour hot water on the surface of the tire. Use normal temperature water to pour the surface of the tire pattern, then start the car, drive at low speed for a period of time and then drive at normal speed. After driving, check whether there are hard objects such as stones, iron blocks or nails in the tire grooves. If there are any, clean them up immediately.
Pay attention to wear marks
The traction and grip of new tires and old tires are very different. Those tires that are very worn out, even winter tires, cannot function on ice and snow. Therefore, the tires should be replaced in time according to the wear condition. All tires have abrasion marks at the tread depth of 1.6 mm. Where there is abrasion mark, there is a small boss. This boss is called "tread wear mark". There is "tread wear mark" beside the boss. Abbreviation "TWI". Under the premise of normal use, the tire wear reaching this raised area indicates that the tire needs to be replaced.
Tips: Selection of tires for icy weather and icy roads
Most car owners have the impression that the traction and grip of wide tires are greater than that of narrow tires, so those luxury cars often choose wide tires with better handling. However, the conditions of icy weather and icy roads are different from those on dry roads. In icy weather and icy roads, the traction and grip of tires do not rely on the friction between the tires and the ground, but rely on the tire pattern to penetrate deep into the ice and snow. Obtained by biting with ice and snow. Ordinary tires, whether they are wide tires or narrow tires, due to the characteristics of their patterns, the tread has a larger ground contact area and lower pressure, and the tread pattern is difficult to penetrate into the ice and snow, so the traction and grip are lower. Only winter tread tires can ensure that they can effectively cut into the ice and snow, ensure that they have sufficient traction and grip, so as to ensure the safety of the car.
