Is a tire pressure of 220 acceptable in summer?

[LeNevaeh]

Summer tire pressure of 220 is not acceptable. According to the international GBT2978-2008 standard, the standard tire pressure should be between 2.4-2.5 bar. A pressure of 220 is below the minimum standard value, so it is not normal. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to feel heavy and increases the risk of veering, compromising driving safety; Increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; Reduces the functionality of the cord and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage to the bead area and abnormal wear; Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout; Increases tire deformation, making the tire sidewalls prone to cracking and generating flexing motion, leading to excessive heat, rubber aging, fatigue in the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear.
