What is 210kpa equal to in terms of air pressure?

[Jason]

An automotive tire pressure of 210kpa is equivalent to 2.1 bar of air pressure. Generally, the recommended cold tire pressure for most sedans and SUVs is around 2.3-2.5 bar. Details are as follows: Standard Tire Pressure: According to the international GBT2978-2008 standard, the recommended pressure for standard tires is 2.3-2.5 bar. Based on the principle of thermal expansion and contraction, in summer, the pressure can be adjusted 0.1-0.2 bar lower than the recommended value, while in winter, it can be adjusted 0.1-0.2 bar higher. Low tire pressure results in shorter braking distances and better grip during turns, but it also increases fuel consumption. Effects of Incorrect Tire Pressure: Both underinflation and overinflation negatively impact tire lifespan. Underinflated tires experience increased radial deformation, excessive sidewall flexing, and shoulder wear, leading to higher temperatures and significantly reduced tire life. Overinflated tires become overly rigid, reducing deformation and contact area, which increases pressure and wear on the tread center, causing central wear and compromising comfort while shortening tire lifespan.
