Can You Drive with 120 kPa Tire Pressure?
1 Answers
Tire pressure of 120 kPa is drivable, but the vehicle can only sustain it for 30-50 km. You should replace the tire or refill the air as soon as possible. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and easy deviation, which are factors detrimental to driving safety; Increases movement in 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 between the tire and rim, resulting in damage to the bead area and abnormal wear; Multiplies the 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 lead to a blowout; Increases tire body deformation, making the tire side prone to cracking, while generating flexing motion, leading to excessive heating, accelerating rubber aging, cord fatigue, and breakage, and increasing the tire's contact area, accelerating shoulder wear. Methods to address insufficient tire pressure: If no damage is visible, simply inflate to normal tire pressure and reset the tire pressure system; If the tire is found to be punctured during inspection, drive to a tire shop promptly for repair and then reinflate; If the tire pressure warning reappears after some time of inflation but there is no puncture, it may be due to air leakage caused by rim deformation. It is recommended to check the rim and replace it.
