Weight of air vs. Nitrogen
So I made an amazing discovery today. I got my new Sailuns partially installed today (so far). When I took the old tires and rims to Discount Tire, they were easy to lift and move into my truck. Wh...

Atom for Atom, Nitrogen is Lighter than Air

OK some real numbers the molecular weight of air is about 29 g/mole, the weight of nitrogen gas (remember is is N2 and O2 not N and O) is 28 g/mole. 28/29 is about .965 some you save a whopping 4.5% of the weight of the gas. My educated guess is that there is only 3 or 4 moles of gas in a tire, probably less. And so you save 4 grams of weight and it takes about 30 grams to make one ounce.
