What happens if tire pressure is too low in snowy winter?
1 Answers
Low tire pressure in snowy winter can affect driving safety, and the tire pressure should be adjusted promptly. Reference standards for adjusting tire pressure: According to the international GBT2978-2008 standard, the standard tire pressure is approximately 2.4-2.5 bar for standard tires and 2.8-2.9 bar for reinforced tires. In winter, it is advisable to slightly increase the tire pressure by about 0.2 bar based on the standard tire pressure. Always use a pressure gauge to check the pressure to avoid overinflation, which can cause tire blowouts. Effects of low tire pressure: It significantly increases friction between the tire and the ground, causing a rapid rise in tire temperature, softening the tire, and drastically reducing its strength. When driving at high speeds, this can lead to blowouts. It also increases tire deformation, making the sidewalls prone to cracks and causing flexing movements, leading to excessive heat buildup, accelerating rubber aging, fatigue in the cord layers, and cord breakage. Additionally, it increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
