Is a tire pressure of 2.8 high in summer?
1 Answers
Summer tire pressure of 2.8 is very high. 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. This is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the tire pressures for different tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: Should not exceed 3.5bar. Hazards of excessive tire pressure: The friction and adhesion of the tires 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 body vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and 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 the impact can cause internal cracks and explosions, leading to tire blowouts.
