Nitrogen is more stable than oxygen.  What does this mean and why should you care?       Oxygen expands and contracts (Three time more than nitrogen) as it gets hotter and cooler. This often sets off the TPMS light.  This light is telling you that your tire pressure isn’t what it should be.    As a result of the oxygen in your tires, you may go from having the right tire pressure, to not enough tire pressure, to having TOO MUCH tire pressure.  This can be pretty dangerous.  

Nitrogen doesn’t expand anywhere near as much as oxygen and nitrogen molecules are much bigger and don’t “leak” through the tire.  I hear from people all the time how nitrogen in their tires gives them a much smoother ride too. 

Wikipedia has a pretty good description of what the TPMS system is:  http://en.wikipedia.org/wiki/Tire-pressure_monitoring_system

And at the nitrogen institute, they list some pretty interesting benefits:  http://www.getnitrogen.org/

Yes, I sell nitrogen, but I also just give it away to my customers.  It’s a question of safety for me.  For them, its a matter of better gas milage and their tires lasting longer.  -Adam Ford, Owner
