What is the reason for low tire pressure in cold weather?
When the weather gets colder and the temperature drops, the air in the tire will be affected by the temperature, causing the tire pressure to decrease. In cold weather, the tire pressure of car tires should be appropriately increased by about 0.2 bar based on the standard air pressure of car tires. The harm of low tire pressure: the coefficient of friction with the road surface will increase and fuel consumption will increase; it will lead to unfavorable driving safety factors such as a heavy steering wheel and easy deviation; it will increase the amount of movement of various parts of the tire, and excessive rolling will cause abnormal heating of the tire; cords and rubber The effect is reduced, causing delamination or excessive friction between the cord and the rim, causing bead damage and abnormal wear; the friction between the tire and the ground doubles, the tire temperature rises sharply, the tire becomes soft, and the strength drops sharply. If the vehicle is traveling at high speed, it may cause a tire blowout; the deformation of the tire body will increase, cracks will easily appear on the sidewalls, and buckling movement will occur at the same time, leading to tire overheating, rubber aging, tire cord fatigue, cord breakage, and increased tire contact. area, accelerating tire shoulder wear.
