Nitrogen is not lighter than 'air' and the molecules are not larger....check your periodic charts. The only benefit of using Nitrogen is that it doesn't absorb water and therefor will have a more predictable increase in tire pressure as it heats up. Possibly there could be slightly less oxidation on the inside of the tire but since the atmosphere already is ~78% Nitrogen, I really doubt that would show any benefit.
