The cold winter is coming. In addition to feeling cold in the wild, you are also very easy to get hurt when you accidentally touch hard objects. The items that were elastic in summer also become very stiff in winter. What about special care due to seasonal changes?
Winter tires are used in different seasons, and the requirements for tire pressure and tread depth vary. Winter tire pressure can be 10 to 15% higher than the standard inflation pressure.
Before driving, check whether the tire grooves are covered with ice and snow. Pour hot water on the tire surface. Water the surface of the tire tread with room temperature water.
Tire punctures also occur in winter
Most people think that punctures are only a problem in summer, but this is not the case. There is a risk of a tire blowout. In winter, when the weather is cold and freezing, the rubber and plastic will become stiff, and the tires will be stiffer than in summer. Even though many cars are equipped with all-season tires, the icy and slippery roads will also test the grip of the tires. Generally, there are two common cases of tire blowout in winter: one is when the vehicle is hit by an external foreign object or is cut on the road, resulting in a tire blowout; ignore. Nowadays, family cars are basically equipped with radial tires when they leave the factory. The airtight layer and the outer tire are closely combined, and there is no inner tube. Therefore, when the tire is accidentally punctured, the gas inside the tire will not leak light at once, but slowly leak. However, when the air pressure is reduced to a certain level, the deformation on both sides of the tread will increase, the tread pattern will be excessively worn, and the carcass will eventually be twisted and deformed because it cannot withstand the excessive pressure, which will eventually lead to a tire blowout.
How to choose tires on icy roads in winter
Most car owners have the impression that wide tires have greater traction and grip than narrow tires, so those luxury Cars mostly use wide tires with better maneuverability. 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 depend on the friction between the tires and the ground, but on the tire pattern to penetrate into the snow and ice. Obtained by intertwining with ice and snow. Ordinary tires, whether they are wide tires or narrow tires, have a large ground contact area and low pressure due to the characteristics of their patterns. Only winter tread tires can ensure that they effectively cut into ice and snow, ensuring that they have enough traction and grip to keep your car safe.
Tips: Pay special attention to the cleaning of tires before and after driving in the cold winter. Before driving, check whether the tire grooves are covered with snow and ice, and if so, clean them up. If the ice trapped in the groove is very hard, it cannot be forcibly pryed or poured hot water on the surface of the tire. Just use room temperature water.
