Nitrogen Tire Top Off Kit
I am in search of a nitrogen topping off kit that could be carried in one's vehicle that could successfully store the unused portion until needed without leaking. We just purchased our DENALI and when...

I also know that Nitrogen filling is not worth the monney, but it wont hurt to use it also.
But when you would have a Nitrogen cilinder together with a pressure device like you put on a compressor , would be handy in use, and wont fail like a small cheep compressor.
Normal cylinders for nitrogen are filled with 200 bar/2900 psi?.
Sorry I go on in European standard, 5 Liter ( 1.5 gallon??) cilinder then would hold about 1000 liter of Nitrogen at 1 bar/14.5psi.
This would be eanaugh to fill a large trucktire to 10 bar/145psi.
And its only to fill up, so would last the livetime of motorhome, i think.
But this would also go if you filled this cilinder with compressed outside air to 200 bar.
Then the water as humidity , would condens and go to botom of cilinder, and wont come out when you fill tire.
Then you would also have practically dry air in tire, wich to my conclusion is also not needed.
In Holland , where I live ( Europe) , there is a foundation "band op spanning" wich first filled on the road with Nitrogen, but found out also that nitrogen gives no additional benefit, and now uses compressed air in cilinders.
I had contact with the founder , but he wrote me that most cilinders are only for hire, and if for sale, verry expensive.
And then a good compressor is cheaper.
Filling Nitrogen filled tires with normal air is no problem.
Theoretically you chanche the ratio Oxigen/Nitrogen a little, but effect is marginal, and so you dont have to let the tires be refilled with nitrogen at home to get the 100% N2 in it.
Its even impossible to fill a tire with that 100% Nitrogen.
When filled there is already normal air in the empty tire with 80% N2 and 20% O2 at 1 bar/14.5 psi.
Example , tire filled with 9 bar overpressure( as you read from gauge), is in real 10 bar ( 9 bar above the 1 bar outside pressure)
Then Oxigen % becomes 2% instead of 20% in outside air.
Also Nitrogen filling is nowadays often done with a device that is placed on a compressor system , wich only gives 95% Nitrogen.
And probably also then some water in the filled air.
