SCAM and proven

Name and shame - that's a hell of a hard sell for something that has little if any benefit.

...the principal benefit of using Nitrogen is that the tyre pressure will vary less with temperature changes (compared to regular compressed air).
Important on a racetrack where 1-2psi difference might equate to winning or not... Almost pointless on the road.
This explains it all nicely (hint, its a scam) -

So you're saying that Charles's Law applies less to Nitrogen than other gases? Why would that be?
I have a family member who runs a garage and sells this service. He is convinced it works and sells it genuinely because of that. But to me it's as convincing as homeopathy.

Sorry @6FIEND, they've slipped you some of the Kool-Aid while you weren't looking...
There is something in it due to the water vapour present in locally produced compressed air v's dry nitrogen. That would vary by season.
I think most people are better off using air and checking regularly. I've had less trouble from slow leakage than random nails and TEK screws. Sticking Nitrogen in and thinking it fixed something gives a false sense of security.
Agree with everything everyone above said.
Nitrogen still leaks, but oxygen passes through rubber at about twice the rate. Nitrogen will still leak if your valve is faulty or you have a puncture or whatever. All the benefits sold to the OP are potentially real, but negligible. Most are due to the nitrogen not containing any water. There's no particular reason, apart from that it is pointless, that garages couldn't have water traps on their air compressors.
Another line salespeople may use is that aircraft tyres are filled with nitrogen... that's large aircraft where a set of tyres costs more than my salary, and is partly to reduce flammability, partly to reduce leakage at high altitude where the pressure differential is much greater, and partly to extend the life of the tyre. Light aircraft just use air in their tyres.
Ge0rge:
"Would I like to pay extra to have my tyres filled with nitrogen?"
What he really meant to say was..
"Would you like to pay extra to have your tires filled with nitrogen?" "otherwise I'll fill them with this moisture laden air that's come past our un-serviced water trap through an oily airline that's run our impact driver"
"and then your TPMS will fail a week from now"
Not to mention that they aren't filling said tyres in a vacuum, so whatever air was already sitting in there (1 ATM I'm guessing) when the bead seated will remain in there anyway.
I do race, and I don't bother with Nitrogen filling. Partly because of negligible benefit, partly because CBF, mostly because <Insert Nitrogen scammer of choice here> doesn't tend to have outlets at rally service parks or pit areas that tend to be in paddocks on back roads.
If nitrogen doesn't leak but air does, surely the easiest solution is fill up with air, then everything that is non nitrogen will leak out, leaving a nitrogen filled tyre for free
I found this old Tiff from Fifth Gear clip on the subject.

Fully, 100% agree with his last comment

You do realize that air is about 80% nitrogen right?
Wiggum:
You do realize that air is about 80% nitrogen right?
You do realise that once the other 20% leaks out, it's 100% nitrogen right?

Well the 20% oxygen/Co2 is not going to leak out by itself, without taking the nitrogen with it.
