Yes, you can add oxygen to a tire after it has had nitrogen in it. Bring the vehicle back to where you filled it with nitrogen and they ought to drain and refill it for free.
"Topping off nitrogen filled tires with compressed air is no problem. We recommend that you use nitrogen in your tires whenever possible, but if you run into a situation where you can’t get it, no problem. Go ahead and “top-off” your tires with air. Later, you can return to your dealer to have your tires purged of the air and refilled with nitrogen."
Here is a very informative website (American, and Canadian versions available) about the benefits of Nitrogen, who uses it, etc.
Nitrogen in Tires : Information about Nitrogen Tire Inflation News, Benefits, Generator Dealers, Location Finder & More
To summarize:
1. Any vehicle tire can use it
2. You can add air to 'top-up' if required.
3. Increased fuel economy (less rolling resistance)
4. Increased tread life (less rolling resistance - tire loses less psi)
5. Decresed wheel / belt wear = increased tire life
6. Inflammable - does not add oxygen... (a burning tire is difficult to put out)
7. and lastly, you get cool little green valve covers (lol)
Hope this helps,
Cheers,
Interesting link...I watched the Leno Video on Nitrogen use in tires....:Flash:
Man that guy has a lot of really nice cars!
Thanks for the link.
