Is 3.0 bar tire pressure too high for Wuling mini truck?

[Correia]

Wuling mini truck's tire pressure of 3.0 bar exceeds the standard value and is relatively high. The standard should be maintained between 2.2 bar and 2.8 bar. Tire pressure is crucial for tires. Both excessive and insufficient pressure will shorten the tire's service life. Here are some key points about tire pressure: 1、Low tire pressure: Increases tire body deformation, easily causing cracks on the tire sidewalls while generating bending movements. This leads to excessive heat buildup, accelerating rubber aging, fatigue of the cord ply, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear. 2、High tire pressure: Causes excessive stretching deformation of tire cords, reducing the tire body's elasticity and increasing the load during driving. In case of impact, it may lead to internal cracks and blowouts. Additionally, excessive pressure accelerates tread wear and reduces puncture resistance.
