One tihng to keep in mind is that Fox news is often refered to as Faux (Homonym) news. Their accuracy rating is not good.
This article seems to underscore that "Faux" image, that is to say it's faction (Fact and fiction mixed)
There does indeed seem to be some benefit from using either CO2 or Nitrogen to inflate tires, or should I say some slight benefit. I've been argued with on this (By someone who sounded good but missed a few factsl, oh well) It is my understanding that the bit about the nitrogen molicule being a bit less prone to "Seepage" is true. Tires go flat, that is what they do, if you don't believe me check your spare, odds are. it's flat. Not out in the sun so it's not sun damaged, not running over things so it's not punctured, but it's flat because the air has not leaked out, but seeped out right through the tire.
Some folks have tested air in tires and found the concentration of nitrogen increases from 78% on first fill to a higher number, this is because the smaller gasses seep out faster
So what does this mean.. Well, instead of checking pressure every week, you can perhaps go 8 days.
The fiction part is "This is important with Tire Pressure Monitoring Systems (TPMS) I can not think of why, with a TPMS if your tire looses pressure, you are notified, quickly and if you carry spare air (I do) you fix it al;so quickly cause that )(*&_(*@&#$ beep beep is annoying
