Filling tires with nitrogen

[Term3]

Well I was just sitting here enjoying a cold one when I started wondering if filling your tires with 100% nitrogen is better because one of the reasons are to put a stop to whatever oxygen does to the rubber inside the tire. So then what about using 100% Argon?? Is this a valid idea or is my pile of empties too large??

Air is 80% nitrogen and available everywhere, at all times of the day.

Nitrogen is not.

Nitrogen is nice because it does not leak out like air. however nitrogen tires are not very comfortable to ride on if you drive down bumpy roads. unlike air nitrogen does not displace and absorb like air does. if you fill a tire with 100% nitrogen you will feel a difference in the ride. I had a vehicle come in my automotive class when i was at college with 100% nitrogen in the tires and driving over the floor lift felt like i ran over a huge rock with nothing but a frame holding the car instead of having suspension
Edit: also dont know about other places but in spokane there is only about 2 places you can get nitrogen put into your tires and its not free...

I'm just not sold on the whole nitrogen thing. I've had tires in the past filled with it and to me I really didn't notice a difference at all. My mom has nitrogen in her tires and again it does not ride any different to me, when I do actually ride in her car. And nitrogen does leak out like air, how do I know this because she had to take her care to the local tire shop and get one filled back up with nitrogen...yesterday afternoon. And this is not the first time this has happened.

I know in aircraft the tires are filled with nitrogen, but that is only because it does not change pressure at altitude... i guess if you were running 600 psi in your tires and changing alt from sea level to 40 thousand feet and back there may be some benefits... as far as an automotive benefit there may be some benefits, but it may be more of a marketing gimmick...
