Inflating With Nitrogen
Many regulatory agencies require the use of nitrogen when inflating tires for aircraft above a specified Maximum Takeoff Weight (MTOW). Michelin recommends the use of nitrogen when inflating all aircraft tires. Nitrogen provides a stable, inert inflation gas while eliminating the introduction of moisture into the tire cavity.
Aircraft operating procedures for initial inflation and adjustments must comply with applicable instructions as given in FAR 25 or JAR 25.
Oxygen concentration should never exceed 5%.
