Is it safe to drive with a tire pressure of 185?
1 Answers
Tire pressure of 185 kPa is not safe for driving. According to the international standard GBT2978-2008, the recommended tire pressure is 240-250 kPa for standard tires, 280-390 kPa for reinforced tires, with the maximum pressure not exceeding 350 kPa. Hazards of low tire pressure: Increased friction with the road surface, leading to higher fuel consumption; Heavier steering wheel and tendency to drift, compromising driving safety; Increased movement of tire components, causing abnormal heat due to excessive rolling; Reduced functionality of cords and rubber, leading to delamination or cord breakage, excessive friction with the rim, and damage to the bead area, resulting in abnormal wear; Exponentially increased friction with the ground, rapid rise in tire temperature, softening of the tire, and sharp decline in strength. High-speed driving may lead to tire blowout; Increased tire body deformation, prone to sidewall cracks, and flexing movement, causing excessive heat, accelerating rubber aging, fatigue of the cord layers, cord breakage, and increased tire contact area, accelerating shoulder wear. Solutions for insufficient tire pressure: If no damage is visible, inflate to normal pressure and reset the tire pressure system; If a puncture is found, drive to a tire shop for repair and reinflation; If the tire pressure warning reappears after inflation without any puncture, it may be due to air leakage caused by a deformed rim. It is recommended to check and replace the rim.
