Is 280kpa tire pressure normal for a sedan?

[LailaFitz]

280kpa tire pressure is normal for a sedan, as the normal tire pressure range for sedans is between 250 and 280kpa. The effects of low tire pressure are: 1. Increased contact area between the tire and the ground, making the steering wheel heavier and affecting driving; 2. Tires are prone to overheating, increasing the risk of blowouts; 3. The tire body expands, making cracks more likely to appear on the inner and outer sides of the tire; 4. Accelerates rubber aging and increases tire wear. The effects of high tire pressure are: 1. Increases friction between the tire and the ground, reducing tire grip; 2. Affects braking performance and driving comfort, accelerates wear on the central tread pattern, and reduces tire lifespan; 3. Increases body vibration, accelerates tire aging, reduces wear resistance, and increases the risk of blowouts.
