What is the normal tire pressure in bar?
1 Answers
According to standards, the normal pressure for standard tires is 2.4-2.5bar; reinforced tires require 2.8-2.9bar; and the maximum pressure should not exceed 3.5bar. Introduction to tire pressure: Strictly speaking, tire pressure refers to the air pressure inside the tire. Nowadays, many tires are not filled with air. For these tires, the pressure requirements are more stringent. Tires filled with air are affected by seasonal changes. Moreover, tire pressure is closely related to vehicle performance, such as comfort and load capacity, and also affects tire lifespan. Hazards of unstable tire pressure: Air pressure is the lifeblood of a tire. Both excessive and insufficient pressure will shorten the tire's service life. Insufficient pressure increases tire body deformation, leading to cracks on the tire side and causing flexing movements, which results in excessive heat, accelerating rubber aging, fatigue of the cord layer, and cord breakage. It also increases the tire's contact area, accelerating shoulder wear. Excessive pressure causes overstretching and deformation of the tire cords, reducing the tire body's elasticity and increasing the load on the vehicle during driving. In case of impact, it may cause internal cracks and explosions. Additionally, excessive pressure accelerates tread wear and reduces puncture resistance.
