Is a tire pressure of 2.1 normal in winter?

[MakaylaLynn]

Winter tire pressure of 2.1 bar is not normal and requires inflation. According to the international GBT2978-2008 standard, the standard tire pressure should be between 2.4-2.5 bar, with a recommended increase of approximately 0.2 bar in winter. Therefore, 2.1 bar is below the minimum standard tire pressure and requires inflation. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and potential misalignment, affecting driving safety; Increases movement in various parts of the tire, leading to abnormal heat due to excessive rolling; Reduces the functionality of the cords and rubber, causing delamination or cord breakage and excessive friction with the rim, resulting in damage and abnormal wear at the bead area; Multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts; Increases tire deformation, leading to cracks on the sidewalls and excessive heat generation due to flexing, accelerating rubber aging, fatigue in the cord layers, and cord breakage. It also increases the tire's contact area, accelerating shoulder wear.
