My point is that if you don't rotate the air in your tires like you're supposed to, you'll eventually have 99.999% nitrogen anyway.
This is how I win arguments at work and home.

LOL, I want to see your equation! The relative leak rate is several times higher so the steady state for nitrogen ~ 90% or so, and if these are RFTs, you're sure to replace them long before you approch the steady state value!
