How much pressure is released in 3 seconds of manual tire deflation?

[MilaAnn]

Using a valve core wrench for manual deflation, gently releasing air for about 3 seconds can reduce tire pressure by 0.2-0.3bar. Here is additional information: 1. Tire pressure: A car's performance and power are closely related to tire pressure. If the tire pressure is too high, the increased load during driving can easily lead to tire blowouts. Other consequences include increased body vibration, louder tire noise, and reduced driving comfort. When tire pressure is too high, owners may consider manually deflating the tires appropriately, but they must pay attention to the force applied during manual deflation. 2. Manual deflation: If the owner does not have specialized tools at hand, they can only use a valve core wrench or other fine-pointed objects to press against the valve core for manual deflation. The action must be gentle, with constant attention to the applied force. Excessive force or rapid deflation can lead to over-deflation. Prolonged deflation can also result in tire pressure that is too low. During deflation, it is essential to ensure that the tire pressure remains within the normal range, generally 2.4-2.5bar.
