Has anyone/Does anyone use different gasses in their tires? I was thinking something like argon for even heat distribution....

I have used Nitrogen in the past

 

Why not Helium?

 

I prefer Hydrogen Myself.

 

Helium atoms are VERY small, and will escape over a much shorter amount of time than air or even Nitrogen. Ever wonder why a mylar balloon filled with helium deflates over time? Because the helium is actually passing through the pores in the mylar, and those pores are really small.

Nitrogen is the way to go for racing applications. Totally inert gas, no water vapor to worry about, larger molecular structure, etc. . .

Or maybe you were joking

 

Hydrogen and Helium are bad due to their lifting abilities... (and the whole explosive hydrogren part.

Nitrogen would be nice. Argon is lighter and a better insulator, so I figured it would work best.

This was just my stupid ideas because I've got SCUBA gas mixes laying around...

I was I never really have spent much time thinking about why balloons deflate. Only thing I've ever concerned myself with is how to reinflate after IT's deflated... But I guess thats another thread altogether

 

The question is: which one is better Nitrogen or Argon? Nitrogen is much more available (78% of air), but I think Argon would work better.

I can't imagine you will notice any difference between using Argon or Nitrogen. Go with Nitrogen, easier to get ahold of. . . and it's what the big-boys (professional road-racers) use.

 

Actually Argon is easier for me to get (since in SCUBA you are always interested in lowering Nitrogen, I don't have any tanks of it...)
