The maintenance of the tires is of utmost importance. Because of the driving skills and the braking performance of the vehicle, as well as the vehicle's auxiliary safety system, the tire that is most directly in contact with the road and is tested is the tire of the car. Its conditions and performance directly affect the tires. To every moment you drive in the winter, then below we can talk about the inspection of winter tires. Tire inspection is particularly important for winter tire inspection To ensure the inflation pressure, the winter temperature is low, according to the principle of thermal expansion and contraction, the winter owners should appropriately increase the tire inflation pressure to reduce tire wear, but if you are driving on an icy road, the tire inflation pressure is too high will affect the tire The grip, under normal circumstances, uses 10-15% higher inflation pressure than the standard during the cold winter season. In addition, in cold winters, the vehicle often checks the inflation pressure of the tire. When the tire pressure is insufficient, please add it in time. When winter inflation guarantees inflation pressure, tire bulging, tire cracks, and tire cuts, please replace or repair them in time. Special attention should be paid to the wear of the tread and tire edges, early detection and replacement, which is conducive to the safety of our winter trips. . Pay attention to the condition of the tires The traction and grip of the new and old tires are very different. Those tires that wear very badly, even if they are winter tires, do not work on icy and snowy roads. Therefore, the tires should be replaced in time according to wear and tear. The tire has a wear mark at a depth of 1.6 mm. Under normal use conditions, the place where the tire wear reaches this bulge indicates that the tire should be replaced. Note that the degree of wear of the tire controls the speed of travel. In the cold winter months, if it is restarted after parking, the tire must be driven at a lower speed for a certain period of time before starting to run at normal speed. The most important thing is to control the speed of travel. Especially when driving on high roads, do not rush to accelerate or stop the brakes in order to ensure safety. In winter, do not rush to accelerate and stop braking to strengthen the protection. Before and after driving in winter, pay attention to the cleaning of the tires. Before driving, check whether the tire groove is covered with snow and ice. If so, you must clean it up. If the ice in the tire is very hard, do not forcibly excavate or pour water into the tire. Use the normal temperature to pour the surface of the tire tread. Also, check whether there are foreign objects such as stones, iron blocks, and nails in the groove. If so, clean it up in time. Timely tires are cleaned for wide and narrow tires. In winter, the traction of the narrower tires is greater than that of the wide tires. When driving in snow, the traction of the tires does not depend on friction, but depends on the pattern of the tires deep into the snow, and it is obtained by mutual engagement of the snow and ice. On the contrary, the wide contact area of ​​the tire is large, the pressure is small and the pattern of the tread is difficult to penetrate into the ice and snow. How to select the tire is also determined by the situation. If it is really needed, we can choose winter tires or snow tires to travel. When driving in snow, pay attention to the choice of tires. In addition to driving in winter, people will wear snow chains in snow and ice, but everyone must know that the snow chains will cause damage to the tires and shock absorbers. If your tires are flat, it will damage the wheels. Tyre bulging, the life of the tire will be greatly reduced, the owners of the car please note. We can sum up that we should pay attention to driving in winter: 1. Appropriate tire pressure can ensure the safe driving of the vehicle. 2 Check the condition of the tire and find it damaged. Inspect or replace it in time. 3 Pay attention to the tire wear indicator. When the indicator is exceeded, replace the tire in time. 4 control the speed of the vehicle, do not rush to accelerate, brake. 5 Before and after the trip, we must strengthen the tire cleaning work, pay special attention to check the tread pattern. 6 Select the width of the tire according to the condition of the road surface. If it is really necessary, we can choose snow tires to travel. Winter is the season with the highest requirements for tire performance. In addition to paying attention to daily maintenance, it is recommended that the majority of owners, especially those in northern China, should change their tires for winter due to safety considerations in the snow.
