What is the normal tire pressure?

[Lillian]

According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: Should not exceed 3.5 bar. Normal winter tire pressure range: In winter, adjust the tire pressure based on the standard tire pressure for your vehicle, increasing it by approximately 0.2 bar. Normal summer tire pressure range: Generally, use the lower limit of the standard tire pressure. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can be slightly lower than the standard by about 0.1 bar to prevent blowouts due to high temperatures. Hazards of overinflated tires: Reduced friction and grip, affecting braking performance; Causes steering wheel vibration and misalignment, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, leading to internal cracks or blowouts.
