Which is better, 2.3 or 2.5 tire pressure?

[DiJayla]

Both 2.3 bar and 2.5 bar tire pressures are suitable for sedans, as the normal tire pressure range is between 2.2 bar and 2.5 bar. According to the international GBT2978-2008 standard, the general standard tire pressure is 240-250 kPa; reinforced tires require 280-390 kPa; the maximum air pressure should not exceed 350 kPa. 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 veering, 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, excessive friction with the rim causing damage to the bead area, and abnormal wear; The friction between the tire and the ground increases exponentially, causing the tire temperature to rise sharply, the tire to soften, and its strength to drop drastically. High-speed driving may lead to a blowout; Increases tire deformation, making the sidewalls prone to cracking, and causes flexing movements that lead to excessive heat, accelerating rubber aging, fatigue in the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear. Methods to address insufficient tire pressure: If no damage is visible, simply inflate to the normal tire 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 check and replace the rim.
