What is the normal tire pressure range?

[DelKira]

According to the requirements of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5 bar. In winter, the tire pressure should be adjusted slightly higher by about 0.2 bar based on the standard tire pressure. In summer, the lower limit of the standard tire pressure is generally sufficient. If the car is often parked outdoors, the tire pressure can usually be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. The hazards of excessive tire pressure include: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Causes excessive stretching deformation of tire cords, reducing tire elasticity 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, causing internal cracks and blowouts.
