Is a car tire pressure of 2.0 bar normal?
1 Answers
A car tire pressure of 2.0 bar is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5 bar. 2.0 bar is below the minimum value of the standard tire pressure, so it is not normal. 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 that are detrimental to driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the function 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; 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 a tire blowout; Increases tire body deformation, making the tire side prone to cracking, while generating flexing motion, leading to excessive heat, promoting rubber aging, fatigue of the cord layer, cord breakage, and also increasing the tire's contact area with the ground, accelerating shoulder wear.
