Is a tire pressure of 3.0 normal in summer?
1 Answers
Summer tire pressure of 3.0 is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5bar. 3.0bar 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 the braking effect; It will cause steering wheel vibration and deviation, reducing driving comfort; Accelerate the local wear of the tread pattern in the center of the tire, reducing the tire life; The vibration of the car body increases, which indirectly affects the life of other parts; It will cause excessive extension and deformation of the tire cord, reducing the elasticity of the tire body, and increasing the load on the car during driving; The puncture resistance performance decreases. When encountering sharp objects such as nails and glass on the road, it is easy to penetrate the tire, and the impact will cause internal cracks and explosions, leading to a flat tire.
