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?

Many aircraft tires use nitrogen, but they also use special rims with 2 valves. When first filling with N the second valve is used to purge the tire of air.
A friend who owns a tire shop tells me that using Nitrogen in road vehicle tires is an excellent way for him to improve his bottom line.
Aircraft use nitrogen as a safety measure so that a tire will not provide oxygen to to hot landing gear in the event of a malfunction. A Mexicana 727 was lost years ago due to air in the tires. There was a hung brake that overheated and when the gear was raised. The wheel/tire assembly got hot and a reaction occurred between the tire and air contained within.....the tire exploded, mortally wounding the plane.
