Possibly true, but still 3 times the price. I wonder why Michelin
recommends
nitrogen.

No moisture, as may be found in the output of an air compressor.

Even more important, is the fact that there is no oxygen to cause oxidation
in the metal wheel and to affect the rubber of the tire.

Other inert gas is not a problem, but it is usually going to be more
expensive, since many tire shops now have nitrogen/oxygen separators to get
the nitrogen to use in the tires, without the cost of buying all of the
bottled gas.

I would be concerned about using a argon-carbondioxide mix, because of the
fact that there is still oxygen in the mix.
