When vehicles travel on highways with low tire pressure, a series of safety hazards and economic issues may arise. Firstly, insufficient tire pressure increases the contact area between the tire and the ground, resulting in greater friction during driving.
This causes the tire temperature to rise because the increased contact area generates more heat from friction. Overheating tires weaken their strength and increase the risk of blowouts. Therefore, driving with low tire pressure at high speeds significantly reduces vehicle safety.
Additionally, low tire pressure can lead to abnormal and uneven tire wear. When tires bear weight exceeding their rated load, it accelerates the wear rate of the tread, reducing the tire's lifespan. Uneven wear causes instability during driving and decreases handling, posing unnecessary risks to the driver.
Moreover, low tire pressure reduces vehicle fuel economy. When tire pressure is low, the vehicle requires more power to overcome the friction between the tire and the ground, resulting in increased fuel consumption. Conversely, properly inflated tires reduce frictional resistance, allowing the vehicle to use fuel more efficiently and improve fuel economy.
