Is using Nitrogen a bunch of hot air

XwChriswX

I thought it was because Nitrogen molecules are larger than 'air' molecules (Yes I understand Nitrogen accounts for 78% of 'air' but since were talking about it). So that it takes less Nitrogen to fill your tire than compressed air, but that at the same time, it also fills your tires more effectively for even tire wear?

Oxygen molecules are only roughly 3% smaller than Nitrogen molecules. The gases in their elementary form also expand and contract at the same rate which partially debunks the pressure change with temperature claim. I say partially because they will pick up some stability by using purified Nitrogen as it will be free of water vapor. You could essentially use any purified gas as a fill just Nitrogen happens to be the most plentiful and hence the cheapest. I should fill mine with Nitrous Oxide and sell people "hits" of my tires.
