Is a tire pressure of 192 kPa normal in summer?
1 Answers
Summer tire pressure of 192 kPa is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure for standard tires is 240-250 kPa. In summer, when temperatures are high, the lower limit of the standard tire pressure for car tires is generally used as the reference. A pressure of 192 kPa is significantly lower than the normal lower limit, 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 feel heavy and may lead to drifting, which are factors detrimental to 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, resulting in 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 also causing flexing movements that lead to excessive heat, accelerating rubber aging, fatigue of the cord fabric layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulder.
