Nitrogen is sometimes offered as an alternative to air for tyre inflation.
Nitrogen is an inert (non-flammable) gas – basically, nothing more than dry air with the oxygen removed.
Air contains about 78% nitrogen. Because of nitrogen’s inert properties, it is often used in highly specialised tyre service applications and/or demanding environments, such as aircraft and mining applications. Nitrogen is also often used in motor racing.
For normal tyre service applications, nitrogen inflation is not required. However, nitrogen inflation does not harm tyres and may marginally contribute to reductions in inflation loss by permeation. Nevertheless, nitrogen will not prevent any inflation loss caused by punctures, tyre/rim interface (bead) leaks, valve leaks, valve/rim interface leaks, wheel leaks, etc.
Whether inflated with air or nitrogen, regular inflation pressure maintenance remains critical and necessary. Use of nitrogen alone is not a replacement for regular tyre inflation pressure maintenance.
For any questions or concerns, Continental recommends seeking the advice of a service professional.
