How about using helium. It is lighter than air and will reduce the unsprung weight. It is also cheap. |
even smaller than hydrogen, which has 2 atoms per molecule. Helium will
leak out of almost any container faster than any other gas, due to its small
molecular size.
Apart from that factor, it would be ideal (although very expensive) as it is
inert. It's light weight is not a real bonus however, as even the weight of
air in a tire is negligible, compared to the weight of the tire and wheel.

Air is mostly nitrogen (~78%) and the rest is mostly oxygen (~21%). Long pause. There are two reasons to use nitrogen instead of the same air you breath. One is that nitrogen is typically dry compared to room air. |

The other is that oxygen is a corrosive gave and MAY cause earlier internal aging of your tires and any corrosion-labile things inside the wheel/tire assembly. |

Given that the outside of you tires is nicely bathed in air, I see little point in worrying about oxygen inside the tire. |

If you have too much money, go waste it on nitrogen fills if you like. Just don't expect any benefit. True. Automotive pressure not to significant. Higher performance |

Uh, no such thing as a Helium molecule. You're splittin hairs -- in this case the atom and the molecule are one and |
