Nope... just a selling (money making) feature. I remember this trick back in the 70's during the first "oil shortage". That made the rounds.. back then too.
Yes, planes do use nitrogen. They also take a heck of a beating and big aircraft travel thousands of feet in the air where it's minus outside, then land in Florida.
Race cars too.. at 220mph, you need it.

Sneakers says you're not really going to notice any changes running nitrogen in your tires. But he also says he thinks there's something to be said for running nitrogen in your tires.

I had new Michelins put on last Sept at Costco on a suv. They put nitrogen in your tires as part of their installation. I don't think I would have paid extra for it if it wasn't included. I've checked my pressure several times myself and they are at exactly 30lbs where they were when they filled them. I began to think my pressure gauge wasn't good so I took to a garage and had them check and 9 months later still have 30lbs pressure in each. Been driving 40 years and never had than experience before.
 
Had Goodrich tires installed on a Tundra in Dec also at Costco. The same story. These same two vehicles with OEM tires had to have air added at least a couple of times a year and sometimes a single tire more than that. The Tundra with the nitrogen still has same pressure as when originally filled. Now this may have something to do with the installation and the tires themselves, but I've ran hundreds of tires in my 42 years of driving and never had this kind of luck.
 
I haven't read any stories of the nitrogen filled tires not giving good results. Lots of people will say scientifically it doesn't make much difference but the proof to me is my experience. Most of them just read stuff and then tell everybody else they are crazy.

I paid $5 per tire.The nice thing besides less loss of pressure is that I can go there any time and they will check the pressure and if needed will add nitrogen for free.I used to hate checking the tire pressure.

the proof to me is my experience
 
Thanks for your report. In my experience, ordinary air (79% N2) has always been completely reliable and I have seen no need for nitrogen. Any time I have had air pressure problems it was always due to damaged rims or faulty tires. N2 would have made no difference. And the science still holds.

Air has always been reliable for me as well but I still had to add air at least a couple of times a year. Do I need the full nitrogen? Not at all but it is very nice to have have full tires all the time and not have to check nearly as often especially when it's cold as a welldiggers a** out.
 
I wonder if the nitrogen, because of it's molecule density, is less inclined to contract in cold temperatures. Usually when it's very cold tires need a little more air but mine stayed full all winter. This could all be a coincidence of new tires and a great seal/installation job but it sure is a pleasant experience.

I wonder if the nitrogen, because of it's molecule density, is less inclined to contract in cold temperatures.
 
Under "normal" conditions, nitrogen and oxygen molecules both behave pretty much as ideal gases so their density variation with temperature will be substantially the same.
 
The relevant factors are molecular size and molecular speed. Nitrogen molecules are larger than oxygen molecules (by about 6%) so they will be less likely to escape through a "hole" in a single encounter. On the other hand, nitrogen molecules travel a little faster than oxygen molecules for a given temperature (also about 6!) which gives them more frequent opportunities to escape. In the end, it should be pretty much a wash between the two molecules.
 
On the other hand, the air that you pump into your tires has some water content which is not present when you use pure nitrogen to fill your tires. Water vapor accounts for some of the pressure in your air-filled tires and it can leak out more quickly than either nitrogen or oxygen.
 
In any case, I'm glad you're happy with your new tires and your N2!

Need my Nitrogen Tires Filled by dago55

I have been chasing the dealership I purchased my Nissan Versa from about getting my tires filled; since unbeknown to me the tires are filled with nitrogen. Each time I have called the dealership; plus stopped in they tell me the machine is broke. I check with Discount and Big O and they don't carry nitrogen.
 
I live in AZ and my tire light is on and my tires are low...Can you add air to the nitrogen tires without damage. Any ideas, I am getting very ticked off...

You can add regular air to nitrogen filled tires. It will just dilute the nitrogen a very small percentage. Normal air is about 80% nitrogen and 20% oxygen. So by putting air witht the nitrogen you would have just a couple of % oxygen versus about 100 nitrogen. Over time, and without additional nitrogen you would get closer to a regular air mixture.
 
I have had very good luck in Chicago area with two vehicles with nitrogen(nothing added for almost a year in both vehicles). Maybe the high temperature of AZ affect the nitrogen more. I wouldn't know about that but it is certainly ok to add regular air.
