Is a tire pressure of 3.0 bar normal for a sedan?

[StSophia]

A tire pressure of 3.0 bar is not normal for a sedan. According to the stipulations and requirements of the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5 bar. 3.0 bar exceeds the maximum value of the standard tire pressure, so it is not normal. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; It accelerates localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan; Increased body vibration can indirectly affect the lifespan of other components; Excessive stretching deformation of the tire cords can reduce the elasticity of the tire body, increasing the load on the car during driving; Decreased puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and impacts can cause internal cracks and explosions, leading to a blowout.
