Can a tire pressure of 185 be driven on the highway?
1 Answers
A tire pressure of 185kpa cannot be driven on the highway. According to the international GBT2978-2008 standard, the general standard tire pressure is 240-250kpa; reinforced tires are 280-390kpa; the maximum pressure should not exceed 350kpa. 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 prone to deviation, which are factors detrimental to driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of the cord and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage and abnormal wear to the tire bead area; The friction between the tire and the ground multiplies, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a tire blowout; Increases tire deformation, making the tire side prone to cracks, while generating flexing motion, leading to excessive heat, accelerating rubber aging, fatigue of the cord layer, cord breakage, and also increases the tire's contact area, accelerating shoulder wear. Methods for insufficient tire pressure: If no damage is visible, simply inflate to normal tire pressure and reset the tire pressure system; If a puncture is found during inspection, promptly drive to a tire shop for repair and then reinflate; If the tire pressure warning appears again after 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 if necessary.
