[QUOTE="Doctor CAD, post: 851118, member: 65663"] If you fill a tire with air (78% nitrogen) and let the 21% other gasses leak out, you will end up with a tire that has 25 psi of 100% nitrogen left in it. Refill that tire with 7 psi of air at 78% and let the 21% of that 7 leak out, you now should have a tire with 30.4 psi of 100% nitrogen, not bad. Refill and let 21% of the 1.6 psi leak out and now your tire will have 31.65 psi of 100% nitrogen in it!!! Eventually, you'd have a tire with 99.999...% nitrogen in it, probably more than a nitrogen tire filling company can do. Now, this would be true if nitrogen didn't leak out of a tire, but, come on...we all know it does. [/QUOTE]
