What Causes the Tire Pressure of a New Car to Drop to 1.9bar?
1 Answers
The tire pressure of a new car drops to 1.9bar because the vehicle has been parked for too long, causing the tire pressure to decrease. When the car leaves the factory, the tire pressure is usually closer to the upper limit of the safe range. However, as the car remains parked for an extended period, the tire pressure will naturally decrease. Some manufacturers intentionally lower the tire pressure to prevent excessively high speeds. Since the car is new, it requires an adaptation period. During this period, reducing the tire pressure slightly helps prevent traffic hazards caused by high speeds. Tire damage: If there is an issue with the tires at the time of delivery or if the tires are punctured during use, the low tire pressure alarm in a new car should prompt a thorough inspection to check for any tire damage. 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 driving resistance, which naturally leads to higher fuel consumption. Shortened tire lifespan: Similarly, due to the larger contact area with the ground, tire wear is accelerated, reducing the overall lifespan of the tires. Increased risk of blowouts: The rise in friction causes the tire temperature to increase, making the tires softer and weaker. When the tires can no longer support the vehicle's load, especially during high-speed driving, the risk of a blowout becomes significantly higher.
