Is it safe to drive with a tire pressure of 2.2 bar in summer?

It is not safe to drive with a tire pressure of 2.2 bar in summer. According to the international GBT2978-2008 standard, the standard tire pressure for regular tires is 2.4-2.5 bar, and in summer, the tire pressure should generally be at the lower limit of the standard tire pressure range, which is 2.4 bar. A pressure of 2.2 bar is significantly below the normal range, so it is unsafe to drive. Hazards of low tire pressure: Increased friction with the road surface, leading to higher fuel consumption; Heavier steering wheel and a tendency to drift, which are factors detrimental to driving safety; Increased movement of tire components, causing excessive rolling and abnormal heat generation in the tire; Reduced functionality of the cords and rubber, leading to delamination or cord breakage, excessive friction between the tire and rim, and damage to the bead area, resulting in abnormal wear; Exponentially increased 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 a tire blowout; Increased deformation of the tire body, making the tire sidewalls prone to cracking, along with flexing movements that cause excessive heat, accelerating rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
