Unless you pay for nitrogen in your tires and feel the need to justify the
money well spent.
What I understood was that permeation is so small that it's essentially insignificant. And that if one loses considerable air from their tires, it's due to a leak and not air permeation.
Also the main point of the intro example is to show how biased, inconsistent and unscientific consumer opinions can be. Jimmy James from the example used "inaccurate air pumps" before and now only checks pressures 5 months later. So two bad practices which make his findings completely useless. 5 months later the season might have changed from winter to summer, so the temperature difference could make the pressure appear unchanged.
