Doh. You mean 78% NITROGEN.

This thread wouldn't be so entertaining if air were 78% oxygen.

I bought new tires for my car the other day at COSTCO and they use nitrogen for all the reasons mentioned.

Just joking but:

Let's say you fill up your tires with air (78% nitrogen) and the other 22% leaks out. Then pump more air into your tires - which you will now have about 95% nitrogen and 5% of other. Now the 5% of the other leaks out and you pump up your tires again now you'll have 99% nitrogen.
