I normally drive the car once every few weeks and I have noticed that the nitrogen maintains air pressure. Everytime I get into the car, the air pressure is as I left it. With normal air, the air pressure dropped extremely low when stored.
I will though tell you...performance or fuel millage...definitely no difference like they promote it to be..

Okay, here's a question for someone smarter than me (which is not a very exclusive group, unfortunately)........
If the nitrogen leaks out at 1/3 the rate of oxygen and you lose some air from the tire don't you end up with a higher concentration of nitrogen than you originally put in?
And if this process of leaking and adding air continues over time wouldn't you eventually end up with almost all nitrogen (providing the tire is never purged)?
Just a thought that seems to make logical sense but is probably scientifically flawed.
Help me out here.

Yes, but not enough nitrogen to provide the same psi you started with when it was "air"

Ive actually considered putting helium in my tires. I think being able to float around the city is pretty cool. I was wondering what is the best way to get back to the ground without getting out the car to let helium out of tires.
Sounds like you guys about nitrogen!!!!

I think I understand what you're saying. But you continue the cycles of adding 'air' to keep the pressure where it belongs (30psi). As the tire continues to leak (mostly nitrogen) and you continue to add 'air' which is 78% nitrogen and 21% oxygen, the concentration of nitrogen should continue to increase with every leak/fill cycle. Is that correct?
