Not nitrogen , again !
If at sea level I removed the valve stem from a tire ,the air inside would equalize at one atmosphere .Replace valve stem and brought tire up to 33 pounds with nitrogen , contents would be 50 percent ...

No, you're not correct.
You don't need a vacuum pump to get 99% N into a tire.
Here's how you do it. Get as much air out of the tire as you can without blowing the bead off. Put the valve stem back in and fill with N.
Bleed all of the air/N out of the tire.
Fill with N again.

Fill with N again.
Each time you do this you get a higher concentration of N into the tire. After about 3 or 4 times you have "pretty much" 100% N in the tire.
Purging.......
That's why dealers charge for Nitrogen filled tires...to cover cost of all that nitrogen being purged.
If they are not purging then they would be charging for services not preformed and a dealer wouldn't do that!
