Nitrogen in Tires - Toyota Yaris Forums

How can a tire be filled with 100% nitrogen?

To do so would first require the tire to be installed on the rim in a vacuum to eliminate any air in the tire/rim before inflating it with nitrogen.

How about helium?

I don't know a whole lot about gases but that would certainly lighten things up. Maybe it wouldn't hold as well? Sorry if this sounds stupid.

I believe it's because Helium molecules are too small and thus they would lose pressure much faster than is practical.

See molecular diffusion.

Thicker molecules like Nitrogen and Oxygen can't escape the tire as easily so they're used instead of Helium.

Good Point

He did deflate the tyre by removing the tyre valve and letting all the air that wanted to escape out. I was merely trying to point out that they used bottled Nitrogen rather than the stock 78% we breathe in the air.
