Air consists of approximately 78% nitrogen, nearly 21% oxygen, and traces of water vapor and noble gases like neon and argon. Using pure nitrogen in your tyres offers several advantages. Firstly, nitrogen molecules are larger than oxygen molecules, making it less likely for nitrogen to migrate through the tyre rubber. This results in more stable tyre pressure over longer periods, which can enhance fuel efficiency, improve handling, and extend tyre lifespan. Additionally, nitrogen is less affected by temperature changes, helping to maintain optimal pressure regardless of weather conditions.
