How to check tire pressure in winter?

The weather in winter is cold, shrinking and hot, so generally speaking, the tire pressure should be appropriately increased in winter. Generally, the tire pressure of a car in winter is 2.5 to 2.8 kilograms. In order to ensure driving safety, when the temperature drops, you must remember to carefully check the tires, often clean the inclusions on the tire tread, try to avoid using tires that have been mended more than once, and replace tires with larger wear and different brands and patterns. In addition, having good driving habits can also reduce tire wear, such as avoiding starting too hard, turning sharply, braking suddenly, driving at high speed in bad road conditions, getting on and off the curb and scraping obstacles when parking. People walk on their legs and cars run on four wheels. Abnormal tires are just like human legs, so it is inevitable that there will be difficulties when moving forward. At this time, it will not only bring inconvenience to travel, but also be prone to accidents in cold or rainy and snowy weather.

"Winter is a season that is particularly harmful to tires." Automobile manufacturers usually assemble AIISeason tires for vehicles, which compromise the characteristics of summer tires and winter tires. Therefore, when driving in winter, we should pay special attention to tire pressure and maintenance to avoid accidents when not in use. Among them, the tire pressure of ice and snow pavement should not be too high. Due to the low temperature in winter, the tire pressure will also decrease due to the influence of thermal expansion and cold contraction. At this time, if the tire pressure is improperly increased, it will not only increase the fuel consumption of the car, but also accelerate the wear of the car tires. But the air pressure of the tire should not be too high, otherwise the friction between the tire and the ground will be greatly reduced and the braking performance will be weakened. In winter, the tire pressure should be increased or decreased according to the manufacturer's standards and road conditions. If the road is icy and slippery, the tire pressure should not be too high. Although wear can be reduced, high tire pressure will affect tire adhesion. In order to increase the adhesion of tires, it is necessary to reduce the tire pressure appropriately. When will it increase? When will it be reduced? It depends on the road conditions. If there is ice and snow on the road now, it is necessary to appropriately reduce the tire pressure and increase the ground friction, otherwise it will affect the braking performance of the tire. Always clean up the impurities on the tire tread "seven points for maintenance and three points for repair", which is a car maintenance secret that every car owner should keep in mind. In winter, it is best for car owners to clean the inclusions in the tire tread frequently, so that hard impurities will inevitably stay in the tire tread, leading to tire rupture or air leakage. In the process of driving, foreign bodies such as gravel will inevitably be mixed in the tire tread. If it is not removed in time, some will fall off for a long time, but a considerable part will become more and more "stubborn" and get deeper and deeper in the tread pattern. When the tire is worn to a certain extent, these pebbles will even puncture the carcass, resulting in air leakage or even puncture. In addition, the owner should pay special attention when parking the vehicle to avoid the damage of the valve when it comes into contact with external hard objects, resulting in a flat tire. ?

Lack of air is the main cause of flat tire. Most of the common causes of puncture in winter are caused by puncture, which is also one of the most easily overlooked causes of puncture. Today's family cars are all equipped with radial vacuum tires. Even if the tire is accidentally punctured, the gas in the tire will not be completely exhausted in a short time. However, when the air pressure decreases to a certain extent, the deformation on both sides of the tread will increase. Once the tread pattern is excessively worn, the carcass will eventually be twisted and deformed because it can't resist excessive pressure, which will eventually lead to a puncture. I would like to remind the majority of car owners not to neglect the daily maintenance of tires at any time, regularly check whether the tires have nails, cuts, aging, rubber cracking at the valve, etc., and deal with them in time to prevent the lack of sports gas.
