Nitrogen tires

I just bought a 5th wheel. I have yet to take possession of it:), I notice the tires are serviced with Nitrogen. So how do I maintain nitrogen filled tires?
  • if you use air that ties up oxygen, if enough tires are filled with air eventually,,, what will we breath???

    I would fill them with helium, that will make the trailer lighter and get better fuel mileage towing
  • NASCAR uses nitrogen so it must be good. The next time I am going to go 200 MPH I am going to use nitrogen.
  • My old Jeep had nitrogen in the tires from the previous owner. The tires seemed to hold air well but I can't say it had anything to do with nitrogen. Buuuuuuttttttttttt... Lets apply logic to the theory. If the claim is that nitrogen won't leak out of tires and ambient air is 78% then tires should only leak down 22%. If the tires do leak down 22% and you top them off with air you now have 83% nitrogen. Now the tires would only leak down 17%. As the leak down and refills occue you could almost have 100% nitrogen.
    Edit
    I just read the previous post i am guilty of not reading all replies before I post.

    DEAR GOD NO!!!

    That violates the intent of the incredibly smart engineers and voids the warranty of the tires, and is dangerous, becuase it doesn't follow the manual, and risks killing women and children all over the globe!


    That being said- I have HEARD that Nitrogen is better because it transfers heat better (I call bullcrap since 78%N2 has got to transfer a pretty good fraction of the same amount of heat), AND I HAVE ALSO HEARD THAT MAYBE THE PURE NITROGEN DOESN'T LEAK AS MUCH....

    Of course, when I REALLY think about it, if I use 78%N, then the 02 will leak out and the 78% will move closer to pure N.
  • Two choices.
    1. Find a shop that has nitrogen.
    or
    2. Use a nitrogen substitute(78% nitrogen). local air from your home compressor or local gas station.
