What is the normal tire pressure for a sedan in summer?
1 Answers
In summer, the normal tire pressure range is between 2.3-2.5. If the car is fully loaded with 5 passengers, adjusting the tire pressure to around 2.5 is more suitable; for general two-person occupancy, a tire pressure of 2.3 is also normal. Below is relevant information about tire pressure: 1. Tire pressure, strictly speaking, refers to the air pressure inside the tire. There is a label with standard tire pressure indicators on the rear of the driver's side door, which indicates the pressure when the tires are cold, i.e., after the car has been parked for at least three hours or driven no more than 1.6 km. Measuring tire pressure when the tires are cold yields the most accurate results. 2. Air pressure is crucial for tires; both too high and too low pressure will shorten the tire's lifespan. Insufficient pressure increases tire deformation, leading to cracks on the tire sidewalls and excessive flexing, which causes overheating, accelerates rubber aging, fatigues the cord layers, and may break the cords. It also increases the tire's contact area with the ground, accelerating shoulder wear. Excessive pressure overstretches the tire cords, reducing the tire's elasticity and increasing the load on the car during driving. In case of impact, it may cause internal cracks or blowouts. Additionally, high pressure accelerates tread wear and reduces puncture resistance.
