Is 190kpa Tire Pressure Normal?
1 Answers
Tire pressure of 190kpa is not safe for driving. According to the international GBT2978-2008 standard requirements, the normal pressure for standard tires is 240-250kpa; reinforced tires require 280-390kpa; the maximum pressure should not exceed 350kpa. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and potential deviation, compromising driving safety; Increases movement in various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim causing damage to the bead area and abnormal wear; Multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout; Increases tire body deformation, making the tire side prone to cracks, and generates flexing movements, leading to excessive heat, rubber aging, fatigue in the cord layer, cord breakage, and also increases the tire's contact area with the ground, accelerating shoulder wear. Solutions for insufficient tire pressure: If no damage is visible, simply inflate to normal pressure and reset the tire pressure system; If a puncture is found during inspection, drive to a tire shop promptly for repair, then reinflate; If the tire pressure warning reappears after inflation without any puncture, it might be due to air leakage caused by rim deformation. It is advisable to check the rim and consider replacement.
