Your tires are leaking air through invisible microscopic pathways

Why Does Tire Pressure Keep Dropping? · 8:12 · Video: History of Simple Things · Watch at the source

In short: You don't need a nail or a visible puncture to lose tire pressure. This video explains the microscopic reality of how air escapes your tires, revealing that some leaks happen at a level nearly impossible to see with the naked eye.

While most drivers look for physical damage like screws or tears, many pressure drops occur through microscopic pathways in the tire's structure. The air isn't always escaping through a single point of failure; it can seep out at a molecular level.

Understanding this mechanism shifts the perspective from looking for 'damage' to recognizing the inherent permeability of materials. It highlights how even seemingly solid objects have limits when subjected to constant pressure over time.
