Oxygen's molecular weight is about 32, nitrogen's 28, so air with its oxygen content is a little denser than nitrogen. I doubt you could measure a significant difference in the leakage rate. Nitrogen's a current "snake oil" fad for the most part.

nitrogen is not snake oil for the racetrack where tire temps hit extremes. but everywhere else, yes snake oil
