John, I don't know for sure if works or not but Sonja's Lexus has Nitrogen when I bought the tires 5 years Les Schwab did it for free and last week at Costco when she had the tires checked they had only lost 3 to 4 lbs in 5 years. Fwiw I think it works in the AZ heat as her car sits for months and the tires never bounces (could be the tire) watching Schwab do it they mounted the tire then let the air out and pulled a small vacuum on the tire then the nitrogen but paying 5 or 10 bucks a wheel I would go with the air good luck
... It also doens't expand like oxygen does. ...
... On air, I get 10psi rise in tire air pressure on the track in three laps. With nitrogen, only 4 psi! ...
Nitrogen molecules are larger than O2, so they do not leak out of tires as quickly.
Also, there is zero humidity in nitrogen, a huge advantage to tire life. Tires do not like humidity inside them!
Steam expands!!!!!
... Oxygen is needed for corrosion of both metals and rubber. ...
