Why Does the Tire Pressure of a New Car Gradually Decrease?
1 Answers
If a car is left unused for too long, the tire pressure will decrease. When the car leaves the factory, the tire pressure is actually closer to the upper limit of the safe range. However, as the car sits unused, the tire pressure will change. Some manufacturers intentionally lower the tire pressure to prevent excessively high speeds. Since it's a new car, there is an adaptation period during which the tire pressure is slightly reduced to prevent potential traffic hazards caused by high speeds. Tire damage: If there is an issue with the tires when leaving the factory or if the tires are punctured during use, the low tire pressure alarm in a new car should prompt a thorough check to see if the tires are damaged. Hazards of low tire pressure: Increased fuel consumption: Low tire pressure increases the contact area between the tires and the ground, thereby increasing friction and rolling resistance, leading to higher fuel consumption. Shortened tire lifespan: Similarly, the increased contact area with the ground accelerates tire wear, reducing the tire's service life. Increased risk of blowouts: The increased friction raises the temperature of the tires, making them softer and weaker. When the tires can no longer support the vehicle's load, especially at high speeds, blowouts are more likely to occur.
