Is a Tire Pressure of 180 Normal?

[LeTheo]

Tire pressure of 180 kPa is not normal. According to the international standard GBT2978-2008, the recommended pressure for standard tires is 240-250 kPa; for reinforced tires, it is 280-390 kPa. The maximum pressure should not exceed 350 kPa. A pressure of 170 kPa is considered too low and driving should not be continued. Hazards of low tire pressure: Increased friction with the road surface, leading to higher fuel consumption; Heavier steering wheel and increased risk of veering, compromising driving safety; Excessive movement of tire components, causing abnormal heat due to over-rolling; Reduced functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage to the bead area and abnormal wear; Multiplied friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout; Increased tire deformation, making the sidewalls prone to cracking, along with flexing movements that cause overheating, accelerating rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area, accelerating shoulder wear. Solutions for insufficient tire pressure: If no damage is visible, simply inflate the tire to the normal pressure and reset the tire pressure system; If a puncture is found during inspection, drive to a tire shop promptly for repair and reinflation; If the tire pressure warning reappears after inflation without any punctures, it may be due to air leakage caused by a deformed rim. It is recommended to inspect and replace the rim if necessary.
