no oxygen = no internal oxidation for us everyday folks ... but the outsides of the wheels and tires are still in contact with the 21% oxygen that we love and need
I don’t know if there is a tremendous difference in expansion rates between Oxygen and Nitrogen (I am sure that there is some)
Top Fuel dragsters or vehicles trying to set speed records also make sure there are nothing but smooth surfaces on their bodies ... it makes a super slight but important for them difference ... us regular folks don’t care if there is a seam line all the way around our door or that our rear view mirror is flat instead of bullet shaped
If you bought a bottle of nitrogen ... how would you know it was 100% nitrogen (it would be the cheapest inert gas) but how could you tell?
All in all, it really is pretty insignificant benefits to be realized at optimum utilization (except for the Dragsters and Land Speed Folks where a bunch tiny things add up)
That’s kind of what I figured, but I have seen these “free nitrogen fill” signs at various places over the last few years, and the poster in this thread mentioned it.
Just seems gimmicky to me.
But was curious as well, do certain sports car tires require nitrogen or you void the warranty or something?
I’ve never driven a Ferrari or anything like that (probably never will) but maybe that’s the thing, or is it just a pretentious thing that the average Joe is getting suckered into?
We get our gas from a gas supplier and it is certified, and they sell nitrogen (and we use it for forcing air out of pipe lines that we have to flame test, I guarantee there is no oxygen in those tanks) but never thought to hook it up to fill a common tire to be honest.
I think my yard mechanic would look at me like I was nuts if I told him to fill the grader tires with nitrogen, lol. But... I might, just to see his reaction... :)
