What can cause a gradual loss in tyre inflation pressure?

A gradual loss in tyre pressure can occur if there is a foreign body, such as a nail or piece of glass, embedded in the tyre, causing a slow leak. Additionally, driving on the motorway with a missing valve cap can allow dirt and moisture to enter the valve, potentially causing air to escape slowly. Accelerating quickly and frequently, however, does not directly cause tyre pressure to drop. Regularly checking tyre pressure helps identify these gradual leaks early and ensures safe driving.
