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...

The influence of water is not that dramatical .
Once got hold of a spreadsheet in wich maximum partial pressure ( Pp) of water as gas .
At 65 degr F this Pp is 0.3 psi .
AT 113 degr /Pp 1.4 psi wich is average warm inside tire temp when driving about 50/55m/h.
AT 140 degr / Pp H2O 2.9 psi.this is to my conclusions what inside tire may maximally get only by driving when outside temp is 65 degr F.
AT 212 degr , Pp H2O 14.7 psi , wich is boiling point of water at normal outside pressure of 14.7 psi/1013mb.
This it can highly incientialy get in the tire, when for instance using the brakes to often when descending the mountains.
Then dry air would rise about to 1.4 times the pressure filled at freezingpoint of water, would mean for 100psi filled> 140psi and if enaugh liquid water in tire, it would rise to 140psi+ 14.7psi=154.7 psi.
In that situation it is an advantage, because then lesser deflection so lesser heatproduction of the rubber of tire by driving.
The cooling down of rubber then is also worse, because of the smaller temperature differences between rubber and inside air ( or whatever gas-compound).
So in normal situations, the extra rising of tirepressure would only be maximally 2.5 psi.
For a normal car tire with 35 psi filled this can have an effect on riding quality wich you might notice , but for a truckkind of tire like TS has, 2.5 psi is peanuts.
But OK , I also am going off topic here, like most of the 9 pages of reactions.
Lets get back on topic, and that is a Top off kit to use instead of a compressor. And so my question in former post still stands.
That one that had a CO2 fill up kitt, for filling when returning to road from offroad , what does it cost, and how is it made.
Then if we know that , TS can chance the CO2 cilinder by N2 and he has what he wants.
N2 is also a cheap gas.
EDIT: searched back this topic , but could not find the CO2 post, so must have been in another topic on another forum.
