What is considered low tire pressure?
1 Answers
Tire pressure below 2.4 bar is considered low. According to the international GBT2978-2008 standard, the recommended tire pressure for standard tires is 2.4-2.5 bar. The hazards of low tire pressure include: Increased friction coefficient with the road surface, leading to higher fuel consumption; Heavier steering wheel and increased tendency for the vehicle to drift, which can compromise driving safety; Increased movement of various parts of the tire, causing abnormal heat generation due to excessive rolling; Reduced functionality of the cord and rubber, leading to delamination or cord breakage, as well as excessive friction between the tire and the rim, resulting in damage and abnormal wear at the bead area; Exponentially increased friction between the tire and the ground, causing a rapid rise in tire temperature, softening of the tire, and a sharp decrease in strength. This can lead to tire blowouts during high-speed driving; Increased deformation of the tire body, making the tire sidewalls more prone to cracking, along with increased flexing motion, leading to excessive heat generation, accelerated rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear at the tire shoulders.
