Can you save some weight by filling the tires with helium?

I am just waiting for someone to try that... and see how far they get... if they are able to move at all... :lol:

I was joking of course, but your response made me wonder what would happen (setting aside outcomes like the car floating away). Helium expands and contracts too much with temp changes or something?

There was a lot of people thinking about it and trying in the past, but to summarize:
1. Main problem is that Helium atoms are so small, so they leak even through many solids, Helium can penetrate metal in tires and leak through rubber wheels, so you will have to have some super fancy sealant (not sure if one even exist that can withstand constant bending of the tire) or add helium every day.

2. Helium contracts/expands with temperature much faster then air, so to compensate for that your tires would have to inflated to higher pressure to reduce the effects of the temperature.

Cars need to reduce mass, not weight. Helium only reduces weight.

Are you really sure? I thought on the surface of the earth weight is proportional to mass... How is it possible to reduce weight without reducing the mass?

Helium would reduce weight because it pulls up due to the atmosphere. This is tantamount to reducing weight by lifting a car off of a scale using a helicopter.

It would WEIGH less on the scale, but still have the same MASS.

I promise you, helium in the tires is pointless. Helium in balloons is interesting, however. A helium balloon on the moon would fall to the ground, by the way.

Here is one source, but they can also be found used by searching in the tuner forums. I bought mine from a guy who was a drifter.
