Using nitrogen for tires may have it's good points wherther or not there is a dollar charge to it. But what happens if you spend your money on nitrogen for the tires and you have to add pressure to a low tire at some point and there is no place around that can fill a tire with nitrogen?
The money you spent for the nitrogen in that tire is pretty much gone at that point.

I can get free nitrogen when ever I want. We use it on aircraft wheels because nitrogen doesnt expand at altitude like compressed air does. This way when they are up flying, the tires dont explode. 
Even if I couldnt get it for free, I still dont think I would pay for it.

Be sure you drain your air compressor at home regularly (surprising that some people have NEVER drained) and if you're real fussy, put a water trap on the compressor outlet before your hose. I've used air hose where the water was bubbling and spraying out the blower!!
No data to back up it up, but I do think the drier the air, the less pressure change there is due to temperature changes.

It does regulate pressure fluctuation, but only a little. We tried it a few years ago for custom bikes with wide back tires and minimal clearance under the fender. We were told that it would stop the tire from swelling up on a very hot day and keep it from rubbing on the fender or other parts. A couple of the manufacturers were insistant that we offer it, and thought that we should buy a $4,000 N2 osmosis pump/filler. I was skeptical, and we bought a regulator and hoses for $150 and rented a bottle. I'm glad we didn't invest in a filler, because we still had issues with tires swelling and rubbing. Normal passenger tires just don't hold enough air/nitrogen for it to make a difference. Leave it for aircraft, earthmover, and truck tires.

Huge waste of money.The is another one of those attempts for the dealership/nitrogen fill providers to make an extra buck.People get all caught up in the gimmick and believe that their tire life is actually going to be prolonged just because you fill nitrogen or your ride quality is going to be better just because of the nitrogen fill.I read an article a while back and it said something along the lines that every 2 weeks the nitrogen loses only a quarter psi less than a standard oxygen fill.The last time I checked, F1 drivers and nascar drivers were the only ones who needed that type of consistency when going down a track at 180+ mph or taking turns where that quarter pound of pressure dictated whether or not your oversteer or understeer.

We dont even use nitrogen in all the aircraft tires, only on ones rated above 180. Some tires we service are rated at 210 MPH and many of those customers dont want nitrogen.
The main reason for using nitrogen is to keep the moisture out of the tire.
Nitrogen has little to no effect on tire pressure.
One of the main benifits of using nitrogen in a tire is the transfer of heat, moisture tends to transfer heat better than nitrogen (or normal air with moisture in it, nitrogen is very dry), thus the use in jet transports where tire temperature is a major concern (high temp blow out plugs).
Please correct me if I am wrong on this.

Are you a pilot or maintainer? Im a maintainer working on a pilots license and I know for a fact that in the Choppers I ork on that we put Nitrogen in the tires because it is less inert than compressed air and wont exand such as compressed air does at altitude. Compressed air would blow a tire at altitude because of expansion. ;-)

Compressed air will blow at altitude-- thats funny.
Im a Pilot with over 6,000 hours flying as well as a "maintainer"
A&P with IA, several years experience with biz jets.
Compressed air WILL NOT blow a tire at altitude--- flown with tires filled with "air" to 48,000 feet-- not a tire blown.
Never seen, never heard of one, please show me if you have seen one.
Laters.

Im simply telling you what has been the standard since I have been in Aviation. NEVER have we used compressed air in a tire. You may want to read this and reconsider your maintenance procedures. Being a pilot, I would figure for the safety of yourself and your passangers that you would keep track of airwothiness regs (AWR). Here is the one you really need to look into, MR. Pilot.: U.S. Federal Aviation Administration issued Airworthiness Directive 87-08-09
