Is 2.2 bar tire pressure too low for a compact car?
1 Answers
The tire pressure of 2.2 bar for a compact car falls within the range of low tire pressure. Generally, standard tires are used for compact cars, and according to the international GBT2978-2008 standard, the recommended tire pressure for standard tires is 2.4-2.5 bar. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and potential deviation, which are factors detrimental to driving safety; Increases movement in various parts of the tire, leading to abnormal heating due to excessive rolling; Reduces the functionality of the cords and rubber, causing delamination or cord breakage, and excessive friction with the rim leading to damage and abnormal wear at the bead area; Multiplies friction between the tire and the ground, causing a sharp rise in tire temperature, softening of the tire, and a rapid decrease in strength. High-speed driving may lead to tire blowouts; Increases tire body deformation, making the tire sidewalls prone to cracking, and causes flexing movements that lead to excessive heat, accelerating rubber aging, fatigue in the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear at the tire shoulders.
