Personally I can't see the point to it. Air is already approx 78% nitrogen
(and 21% oxygen) and the nitrogen molecule is just a bit bigger than an
oxygen molecule. So, to me, putting pure nitrogen into a tire , as opposed
to plain old air, will have no affect on how fast a tire looses air
pressure.

I believe there is a huge business in trying to find gimmicks for garages,
tire shops etc. to increase revenue.
My former mechanic had magazines for mechanics which advertised all sorts of
things to improve revenue. He no longer could just change my tranny fluid and
filter for $15; it now had to be connected to a multi-thousand dollar
machine to be flushed for $120. He had a machine for everything, and all those
things which should have reduced his labor always made my cost more expensive.
He
could no longer diagnose anything without putting it on the computer ($75),
or align a car without going on another computer ($135). I imagine he will be
selling Nitorgen soonif he hasn't already.
Back in the 60's when I was involved with Naval Aviation a bit, I recall all
the aircraft tires were nitrogen filled. The reason as I recall had to do
with the extreme heat and the fact that fuel vapor could be in the compressed
air, thus causing tire fires etc.
