Is a tire pressure of 250 too high in summer?
1 Answers
Summer tire pressure of 250 is too high. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5bar. 250 is higher than the maximum value of the standard tire pressure, so it is abnormal. Generally, the lower limit of the standard tire pressure of car tires is sufficient. For example, the lower limit of the 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 be reduced, affecting the braking effect; It will cause steering wheel vibration and deviation, reducing driving comfort; It will accelerate the local wear of the tread pattern in the center of the tire, reducing the tire life; The vibration of the car body will increase, indirectly affecting the life of other components; It will cause excessive stretching deformation of the tire cord, reducing the elasticity of the tire body, and increasing the load on the car during driving; The puncture resistance will decrease. When encountering sharp objects such as nails and glass on the road, they can easily penetrate the tire, and the impact will cause internal cracks and explosions, leading to tire blowout.
