Is a tire pressure of 2.8 normal in summer?
1 Answers
Summer tire pressure of 2.8 is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5bar. A pressure of 2.8bar exceeds the maximum value of the standard tire pressure, so it is not normal. 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 avoid 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; It accelerates the local wear of the tread pattern in the center of the tire, reducing the tire's lifespan; The vibration of the car body increases, indirectly affecting the lifespan of other components; It causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load the car bears while driving; Puncture resistance decreases. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and the impact can cause internal cracks and explosions, leading to a blowout.
