Is a tire pressure of 250 kPa too high?

[Lilliana]

A tire pressure of 250 kPa is not too high, as this value falls within the normal range. A tire pressure of 250 kPa is equivalent to 2.5 bar. According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: standard tires should be inflated to 2.4-2.5 bar; reinforced tires should be inflated to 2.8-2.9 bar; and the maximum tire pressure should not exceed 3.5 bar. Tire pressure is critical for tire performance. Both overinflation and underinflation can shorten the lifespan of a tire. Underinflation increases tire deformation, leading to cracks on the sidewalls and excessive flexing, which generates heat and accelerates rubber aging. Overinflation causes excessive tension on the tire cords, reducing elasticity and increasing the load on the tire during driving. This can lead to internal cracks, blowouts, accelerated tread wear, and reduced resistance to punctures.
