Can I continue driving with a tire pressure of 175?
1 Answers
A tire pressure of 175 kPa is not safe for driving. According to the international standard GBT2978-2008, the recommended tire pressure is generally 240-250 kPa for standard tires and 280-390 kPa for reinforced tires. The maximum tire pressure should not exceed 350 kPa. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Heavier steering wheel and increased tendency for the vehicle to veer, which compromises driving safety; Excessive movement of tire components, causing abnormal heat due to over-compression; Reduced 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; 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 under these conditions may lead to a blowout; Increased deformation of the tire body, making the tire sidewalls prone to cracks, and generating flexing movements that lead to 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. Solutions for insufficient tire pressure: If no damage is visible, simply inflate the tire to the normal pressure and reset the tire pressure monitoring system; If a puncture is found during inspection, drive to a tire repair shop promptly for a patch, then reinflate the tire; If the tire pressure warning reappears some time after inflation without any visible puncture, it may be due to air leakage caused by a deformed rim. It is recommended to inspect the rim and replace it if necessary.
