Interesting comment. You are correct, that if what the nitrogen proponents say is true, then the Nitrogen concentration in the tire should increase over time and the need to provide make-up air should decline over time. It would be interesting to have someone take an air sample out of a tire when it is worn-out and being replaced to see what the Nitrogen percentage has become over the life of the tire.
Not worth it for an individual to do, but it might be an interesting test for an auto magazine to write about. If the nitrogen content really does increase, it would be a confirmation that the O2 preferentially diffuses through the tire. But if the Nitrogen content does not increase...
