inflating tires on rv with nitrogen, good idea?
I'm interested in hearing comments on using nitrogen in tires on my rv, supposed to run cooler and maintain air pressure better. Any comments would be appreciated. Tom

I recall walking into the squad room at work thinking I might be able to add to the discussion there... ... Turning around, and walking out cause the level of mis-information in that room was way beyond my ability to cope with.
Why do I get that same, exact feeling here?
Statements like "My tires do not loose pressure over time"
Statement like Nitrogen maintains constant pressure no matter the temperature or altitude.
I mean, I am not sure when exactly I learned better than that but I very strongly suspect my age still had but a single digit.
First: As altitude goes up, the "outside" pressure on the tire, normally about 14.696 PSI at sea level) goes down, this is how a barometric altimeter knows how high it is. This means your 100 PSI tires may now meter out at a higher pressure all other factors being the same.
And all gasses ALL OF THEM, become more active when heated, and this translates into higher pressures.
So "Absolutely no change" is thus false.. HOWEVER had the person simply said "Less change" I could accept this.
Is there a benefit... Very likely yes.. Is it worth the cost, Very likely NO.
