Michelin recomends inflating tires with nitrogen. What about Argon? I
got a bottle of argon I use in Mig welding aluminum. Isn't argon
better than Nitrogen? What about the common 75% Argon and 25% CO2
welding mixture?


I'm not sure about the other aspects, but nitrogen is about 1/3 the
price.

And ordinary compressed air is already 80% nitrogen.
But the oxygen and ozone, along with a few other gasses does
accellerate the deterioration of the rubber, and the nitrogen stays in
better than the rest (co2 included) Also more temperature stable,
pressure-wize.


Yeah, I forgot to mention the pressure aspect until after I hit send. But a
lot of the racers love it because they have less pressure rise as the tires
heat up. Probably the best reason I can see for using it in a auto.
Especially in summer.
