If you inflated a vehicles tires with helium would it become lighter?

Answer 1

the first two guys are hua. helium is non-flammable. if you put helium into your tires at normal pressures, they would be ever so slightly lighter, not enough to measure except on the most sensitive scales.

tires would go flat sooner due to helium's smaller molecule though.

Answer 2

Not enough to notice. Helium only provides enough lift by volume to make a 5 gram balloon float, and since helium molecules are so much smaller than nitrogen (78% of the atmosphere), the helium would literally escape between the rubber molecules and the tire would be flat overnight.

Answer 3

Given the properties of Helium, I sincerely doubt you'd be able to fill the tire as it is lighter than air. Helium is lighter than air, and it may go into the tire, but I suspect it would require a large amount to fill it, if at all possible. As also mentioned here, Helium can be ignited, so I doubt even trying this would be wise. Even if you could, it would not lift the vehicle the tires are attached to, as most cars are relatively heavy, weighing at least 1/4 to a full ton.

Answer 4

Hey you have to compress it therefore, more weight. But in any case hydrogen would be better. It's lighter, and your car could go the way of Hindenburg. ;-))

Answer 5

first off helium is a gas not a bright idea because when gas heats up kaboom good bye tire hope this helps but to anser u no it wil not

Answer 6

No, not enough to notice.

And helium won't explode.
