Guess you didn't take any chem or physics in your previous life. Nitrogen is affected by the very same gas laws as air, in the very same way.

Airlines would use nitrogen because:
1) It is easier to get as a dry gas. You don't want a blob of condensate water freezing onto the side-walls, and then becoming a unbalanced mess upon touch down.
2) While not an inert gas, it is more inert in the catastrophic failures that would endanger a plane. The lack of HP oxygen won't feed a fire or decrease the lifetime of rubber or similar materials in the tire.

There are many video's out there that show the danger of welding on a tire rim with a filled mounted tire attched. Same thing could happen on an airplane, a small fire could turn the tire into a big bomb.

A lot of times mechanics have high pressure nitrogen bottles for servicing struts etc. The same can service tires.
Back in the day NASCAR teams used manifolds of nitrogen bottles to power their air wrenches at 180 psi. (And they did zip).
Back then Goodyear used air.
Nitrogen is good for tires, but I use 80% nitrogen myself.

I use the approximately 80% nitrogen mixture myself, as it is so easy to find, and very inexpensive.
