The downside is....at least here in Houston when the temps fall.....So does the tire pressure.Seems its affected by temperature extremes. Sometimes we get an onslaught of folks coming by for refills(for free of course ) because their dash lites are on.My opinion is if no tpms don't bother. But can be good for steel wheels.Most modern alloy wheels will be unaffected buy regular humidty. Theres my two cents

Compressed air can also be dried. Something like this will leave air as dry as your nitrogen. Even one like this would dry air more than enough.

For me this is Bulls....
Telling people that the Nitrogen molecule being bigger and that will not pass true the rubber wall as easily....That there is less moisture......that the pressure will increase by less if temperature increase....
All gaz are subjet to same Lavoisier law as far as gas pressure increase and nitrogen do not react as much with rubber rubber. (what about external air...)
All silly justifications to make money

2. Normal air is 78% Nitrogen, so you want to pay good money for 22% more?

3. In numerous threads on RV forums the most experts agree that this is a gimmmick to get extra money from you.
