Is a tire pressure of 2.7 normal in summer?
1 Answers
Summer tire pressure of 2.7 is not normal. According to the regulations and requirements of the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5bar. A pressure of 2.7bar exceeds 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 for standard tires is 2.4bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1bar lower than the standard to prevent tire blowouts due to high temperatures. 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, reducing tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Excessive stretching deformation of the tire cords reduces tire elasticity, increasing the load on the car during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and impacts can cause internal cracks and blowouts, leading to tire failure.
