1, Ensure the inflation pressure
In winter, the temperature is low. According to the principle of thermal expansion and contraction, winter owners should appropriately increase tire inflation pressure to reduce tire wear. At the same time, however, if the road is frozen and slippery, the tire inflation pressure will affect the tire’s grip. Under normal circumstances, in the cold winter, we recommend using 10% -15% higher inflation pressure than the standard, but can not exceed the maximum inflation pressure specified in the product manual. In addition, in the cold winter, the car mainly checks the inflation pressure of the tires. When the inflation pressure of the tires is insufficient, it should be given promptly.

2, Control the speed
In the cold winter, if it is restarted after parking because the tire is relatively rigid, it must be driven at a lower speed for a period of time before it can be started at normal speed. Of course, the most important thing in winter safe driving is to control the speed. Especially when driving on a highway, pay attention to controlling the speed of the vehicle. Do not rush into acceleration or sudden braking. In this way, safety can be ensured so that cars and tires can be effectively protected during the cold season, thus avoiding traffic accidents.

 3, To strengthen the protection of clean
Before and after driving in the cold winter, special attention must be paid to the cleaning of the tires. Before driving, check whether the tire groove is covered with ice and if it is, it should be cleaned. If the ice caught in the groove is very hard, it cannot be forcibly digging, nor can it be poured hot water on the tire surface. The surface of the tire tread can be poured with normal temperature water, and then the car is started, and the normal speed is used after driving at a low speed for a period of time. After driving, check whether any hard objects such as stones, iron blocks or nails are trapped in the tread groove. If any, clean up immediately.

4, Concerned about wear marks
The traction and grip of new and old tires vary widely. Those tires that wear very badly, even if they are winter tires, cannot play a role on icy and snowy roads. Therefore, the tire should be replaced in time according to the wear condition. All tires have wear marks at a depth of 1.6 mm. Where there is a wear mark, there is a small convex platform. This convex platform is called “tread wear mark” and there is “tread wear mark” beside the convex platform. Abbreviation “TWI”. Under the premise of normal use, the place where the tire wear reaches this bulge indicates that the tire needs to be replaced.

 5, Tyre pressure cannot be too high
 In summer, many vehicle owners pay attention to tire pressure to avoid punctures. In fact, winter should also focus on tire pressure. However, it should be noted that the tire pressure will change with changes in temperature. When measuring tire pressure in winter, it should be measured when the tire is cooled for a period of time while the tire is cooling, and it is best to perform at room temperature. Winter tire pressure can be increased appropriately (control within the specified range). Because of the effect of thermal expansion and contraction, the tire pressure in winter will be reduced. If the tire pressure is unduly increased, it will not only increase the fuel consumption of the car but also accelerate the wear of the automobile tires, it should also prevent the tire pressure from affecting the grip. The control of the car, especially the control of brakes.
