What is the difference between tire pressure 2.4 and 2.5?

[StJohnny]

There is basically no significant difference between a car tire pressure of 2.4 bar and 2.5 bar. The normal tire pressure for a car is between 2.3-2.5 bar, and typically, tire pressure values within this range are considered the safest. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to feel heavy and may lead to drifting, 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 cords and rubber, leading to delamination or cord breakage, and excessive friction with the 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 then lead to a tire blowout; Increases tire body deformation, making the tire side prone to cracking, while generating flexing motion, leading to excessive heat, accelerating rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulder. Solutions for insufficient tire pressure: If no damage is visible, simply inflate the tire to normal pressure and reset the tire pressure system; If a puncture is found upon inspection, drive to a tire shop promptly for repair and then reinflate; If the tire pressure warning appears again some time after inflation but there is no puncture, it may be due to air leakage caused by a deformed rim. It is recommended to check the rim and replace it if necessary.
