Ok, I'll accept that, the tire with nitrogen might read a little lower than the tire with air. But, it won't be by much, air is 78% nitrogen.Ray

I just replaced the tires on my wife's Murano. They were filled with Nitrogen from day one and at 48K miles I replaced the tires with the same OEM brand, Bridgestone Dueler H/T 687, that have a UTQG of only 300. Unreal, they should have lasted 30K. For three years I never had to add air, tires were rotated maybe two times and pressures were checked at each oil change. I credit the longevity to Nitrogen and some to allot of I-95 driving. The tires just do not loose pressure as our breathable air. When I bough my new 2012 Silverado, the service advisor was not even sure if the nitro machine worked anymore and the tire dealer did even offer it. It seems that the Nitrogen fill (extra profit) is just not being offered much anymore.

RayVoy example is perfect in explaining this. I would bet if you used his example you would see more of change in the regular air tire on a digital tire gauge compared to the Nitrogen tire. Probably not enough though to change ride characteristics ect. Nitrogen is cheap so thats why tire shops can "sell" you on the theorys behind it. Is it really worth it? Probably not unless you can get it for nothing IMO.
I use nitrogen at work to purge gas through gas lines.. Its used because the molecules are larger than air and when introduced into a gas line it becomes a Heavy slug to move the lighter air out of an open end of pipe. The natural gas is then put behind the "slug" of nitrogen keeping the air and gas seperate.
We also use it for testing new pipelines.. The new gas mains that I work on are tested at a minimum of 90lbs. for an hour. When I use air compressor air the pressure actually drops about a pound or two over the course of an hour after its change in temperature from being in the ground.. When we test with Nitrogen it doesnt change at all over the course of an hour. I have to document any change in pressure and the utility does not allow any drop in pressure when using nitrogen because of this characteristic. But we generally use an air compressor because of its conveneince and its generally done for an integrity test of the pipeline and not used to find real tiny leaks.

In the air conditioning and refrigerant industry, nitrogen is used to flush and clean the copper lines that might have been contaminated or when an A/C unit is replaced with a modern unit using where the refrigerant is changing to any of the new ozone friendly compounds.

THE AIR WE BREATH IS 78% NITROGEN.
You fill a tire with air which is 78% nitrogen, or you fill a tire with 100% nitrogen. Do you really think that you, or your tire, can tell the difference.
I agree, racers use nitrogen, also, did you know that airline companies use nitrogen in the tires on their planes.
And why?????????? There is no oxygen. Nitrogen will not burn. The 21% oxygen that is in "air" will burn and it will fuel a fire. Something you do not want on a plane, or a race car.
