I had this debate with someone the other day.
I give it a maybe, but not worth the effort/ $$.
I say it is a gimmick by the machine manufacturer to sell machines passed down to the service seller. There is NO way possible to get the tire filled with 100% nitrogen, so it cant be that much better than the 80% nitrogen atmosphere in my opinion. On an idy car, maybe. On my vehicles, no.
