Is 2.8 bar tire pressure normal?

[JadeRose]

Tire pressure of 2.8 bar is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5 bar. 2.8 bar is higher than the maximum value of the standard tire pressure, so it is not normal. Winter and summer tire pressure standards: Tire pressure should be based on the standard tire pressure of the car tires, and can be appropriately increased by about 0.2 bar in winter. In summer, it can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. Whether the tire pressure is normal can be judged by the tire pressure monitoring light: Tire pressure monitoring is the real-time automatic monitoring of tire pressure during driving, and it alerts the driver to tire leaks and low pressure to ensure driving safety. The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top and four small spikes at the bottom, with an exclamation mark inside. The tire pressure monitoring indicator light indicates abnormal tire pressure.
