Nitrogen vs. Oxygen

I got new winter tires for my 300 about 5 years ago. Of course I was not asked if I wanted the Nitrogen, they automatically just put it in. I do have to say that the 3 years I ran them, then gave them to my brother (I sold the car) and he ran them for at least 3 more years. Neither one of us ever had to fill the tire with air. They stayed a constant 35psi. Just my experience with it.

Now with that being said I had to purchase tires for my Durango (thanks to some punk *** that slashed 2 of them). I was curious if Nitrogen was still used. I spoke to the counter guy about it and then at a different time the tech that was installing my tires. They both agreed that it was a gimmick and not worth the money! They didnt even have it at the shop, so they didnt have to try to talk people out of it.
