What Should the Air Pressure Be for All Four Tires of a Sedan?

[EmmettLynn]

The air pressure for all four tires is generally normal when it is around 2.3-2.5. Typically, the tire pressure for small cars and large vehicles may differ depending on the model. Low-pressure tires: Inflation pressure is 0.1471-0.490MPa (1.5-5kg/cm²); Low-pressure tires are generally suitable for private cars; The usual inflation pressure for household sedans is 0.2-0.25MPa. High-pressure tires: Inflation pressure is 0.5-0.7MPa (5-7kg/cm²). High-pressure tires are suitable for large trucks/buses, with an inflation pressure usually around 0.5MPa, while steel-belted tires can be appropriately increased to around 0.6MPa.
