Is a tire pressure of 270 too high in summer?

[StChloe]

Summer tire pressure of 270 is too high. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5bar. 270 is higher than the maximum value of the standard tire pressure, so it is abnormal. Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit of standard tire pressure is 2.4bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1bar lower than the standard to avoid tire blowout due to high temperature. 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 center pattern, shortening tire life; Increases body vibration, indirectly affecting the lifespan of other components; Excessive tension on the tire cords can reduce the elasticity of the tire body, increasing the load on the car during driving; Reduces puncture resistance. When encountering sharp objects such as nails or glass on the road, they can easily penetrate the tire, causing internal cracks and blowouts due to impact.
