Unless they draw a vacuum on your old tires(impossible), those tires still contain moisture and some air even after being filled with nitrogen. I've never used it in my airplanes, motorcycles, or any of my other vehicles and see no reason to start now. I do have an air dryer on my home compressor, and the compressor that I have in my RV. That dry air works fine for the occasional times that I have to top off my tires in the coach or toad.

In case the OP is still in doubt. This is a SCAM OF THE FIRST ORDER!! If you have too much money then by all means go for it. If there was really any truth to the claim that oxygen leaks out of tires faster than nitrogen then over time your tires would tend to fill up with nitrogen anyway. So just air them up a couple of times for free and you will accomplish the same thing you could by paying to have nitrogen injected. IOW you will accomplish exactly nothing. If your tires are leaking - - wait for it - - - - - GET THEM FIXED OR REPLACED.

I run Nitrogen and have a 2200 lb bottle on board just for the tires. I live where it get hot and the tires do not get as hot as friends that we travel with. I have to add about a pound per year so far. This is just a personal choice just like using synthetic oil. If your on board Air compressor has a air dryer and filters then you about the same.

Filling a deflated tire with 95% pure nitrogen yields about a 93% pure mixture. That's more than enough better than 78% to be effective.

To be effective at what? Keeping the tire inflated.
There is still moisture inside the tire even if the nitrogen/oxygen ratio has changed. Sometimes, there is a lot of moisture in there if the mechanic uses any of the liquids to lubricate the rims when the new tires are installed.
I can see an advantage to the shops to have one more thing to sell but I can't see enough advantage to the customers to make it cost effective. A few degrees cooler is not that big of a deal. If a tire is designed to run all day at 130 degrees, what are you gaining by running it at 125 degrees? How does this affect it's life? Has there been a scientific tests to prove any claims, in the real world, rather than the race track?

Air is 78% nitrogen, and I can fill my tires for free!

N2 benefits the N2 $eller much, much more than the N2 buyer/user.

I went to a seminar given by an tire engineer. He said that all tires lose about 2 psi/month !!. If you're putting air into your tires, and checking on a regular basis, then you are increasing the nitrogen any because as others have said, the O2 molecules are 'smaller' then 'nitrogen'. Bottom line, no real difference in performance.

 do i have this right? air starts out 78% nitrogen; oxygen is smaller and is responsible for 2 psi decease in pressure / month because it escapes....then it looks like in the end I will have pure nitrogen at some point in the future....
