Is a tire pressure of 2.2 a bit low in summer?
1 Answers
In summer, a tire pressure of 2.2 is a bit low. According to the stipulations and requirements of the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5 bar. A pressure of 2.2 bar is below the minimum value of the standard tire pressure, so it is abnormal. Hazards of low tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; Causes the steering wheel to become heavy and prone to deviation, among other factors detrimental to driving safety; Increases the movement of various parts of the tire, leading to excessive rolling and abnormal heating of the tire; 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; The friction between the tire and the ground increases exponentially, causing the tire temperature to rise sharply, the tire to soften, and its strength to drop drastically. High-speed driving may lead to tire blowouts; Increases the deformation of the tire body, making the tire side prone to cracking, while also generating flexing movements that cause excessive heat, promoting rubber aging, fatigue of the cord layers, cord breakage, and increasing the tire's contact area with the ground, accelerating wear at the tire shoulders.
