nitrogen does have benefit to it, but i dont think enough to make it worth it for wheeling. i have access to it at home but i dont really use it because im not taking that tank with me wheeling lol

 

Helium, in an attempt to reduce unsprung weight? Perhaps just front or rear separately as a lift leveller? Maybe a little Hydrogen, get the improved flotation and a bigger bang for the buck? Propane for reseating a bead half way to the north pole? Really the Helium is pointless in application. It will leak out and your tires will soften (molecule is very very small) Perhaps set at 35psi on sunday after wheeling. By next friday night it is automatically "aired" down for the next week end of wheeling fun. For daily drivers, air is best. For professional race, nitrogen. All others are snake oil.

 

The wheel/tyre assembly's gross weight may be somewhat less (I doubt by much,) but it's not going to change the rotational inertia of the assembly, and it's not going to reduce the solid mass of the assembly. So, no gain there.

(Filling the tyre with helium may reduce the weight, but it won't do anything at all to the working mass - the gas filling the tyre may be ignored, for the most part, when figuring rotation inertia or rolling resistance. Why? Because it isn't rigidly attached to anything. It's just "along for the ride.")

 

SCIENCE!

 

The little bit of weight you lose from switching from air to helium you could go take a wrench outa the back seat and have the same effect -.-

 

Yawp.

 

Haha

 

I use methane gas in my tires (from my farts)... Makes it was easier to get over tough obsticles and what not.

 

Depends on the science you're talking about.

If it can't be described mathematically, it isn't science - and therefore, isn't important.

Christian Science and Political Science are prime examples of such a misnomer.

"Mathematics is the language in which God has written the Universe." -Galileo

"A man who can't understand mathmematics isn't a man - he is merely an animal that has learned to wear shoes and not make messes in the house." -Robert A. Heinlein, Starship Troopers.
