Dangers of welding wheels.

A lot of the larger mining operations also inflate their tyres with nitrogen. Even doing that will still not prevent one type of explosion (pyrolysis or diffusion, I forget which) because it does not require oxygen for the explosion to take place.

Aircraft tires use nitrogen so when at altitude they don't deflate like air filled tires do, it has nothing to do with preventing explosions. Smaller aircraft that can't climb high enough still use air, but once the aircraft is capable of climbing over a certain altitude, their all nitrogen filled, unless they've come out with something newer in the last decade or so I'm not aware of.

deflation at altitude is not the reason. The nitrogen molecule is larger and tends to keep more consistent pressure overall, but the wheel corrosion is a big deal.

We run tubes so it is not an issue, but all the aircraft rims are alloys, and do corrode readily.

Learned something new, thanks skyking

I run a special mix......

1. Nitrogen — 78 percent
2. Oxygen — 21 percent
3. Argon — 0.93 percent
4. Carbon dioxide — 0.04 percent
5. Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.
