Is a tire pressure of 270 normal in summer?

[Alexander]

Summer tire pressure of 270 is not normal. According to the regulations and requirements of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5bar. 270 is higher than the maximum value of the standard tire pressure, so it is not normal. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and impacts may cause internal cracks and blowouts, leading to tire bursts.
