Is It Possible to Add Air to Nitrogen-Filled Tyres?

Model: (Various brands) Various
Part: Tires

In this video, an expert clarifies a question that many have asked. Some time ago, you may have seen cars with red valve caps. This indicated that those tyres were inflated with nitrogen. What is the advantage of nitrogen inflation compared to air? Nitrogen, being an inert gas, better withstands thermal stresses, reducing the risks associated with tyre overheating; therefore, inflating tyres with nitrogen helps avoid pressure loss. However, if this occurs, it is perfectly possible to re-inflate nitrogen tyres with air. Simply, the nitrogen will dilute, but no harmful chemical reaction will occur.
