Nitrogen filled Tubes

[mister p]

Does anybody use Nitrogen to fill tubes from empty? This would and does make pressure changes due to heat/cold null and void.
Assuming tube material to be non-reactive to Nitrogen. In emergencies air can be added with no adverse effects.
Seems a good idea to me as long as there's a regulator and no leakage.

I used to use a common mix with 79% Nitrogen in mine. It caused no problems with the tubes but I did notice some expansion in sunlight.

Why not 100%?

It was before the Repeal of Boyle's Law, so I was having to make do with what was available.

Oh the huge manatee, the huge manatee..

All that singing.......so Susan is now passing laws. How repealing.
So you had some Nitrogen hanging about..........just enough to fill 79% of your tubes?

Nitrogen is an Ideal gas for sponsons

[mister p]

Yes, that was my thinking too......is it commonly used?

I had my car done and it took ages to fill four tyres, god knows how long a rib would take to fill.

It's good in your defender tyres mr p.

willk, in my excitement at my new invention of Nitrogen I sped read your maths and it's caused a headache. Oh how my head hurts. Now I see the light. I thought you'd only filled your lung tubes 79% and was going to say that was why they had expanded so much. Have you tried Nitrogen in your sponsons?

I once had a Defender,
And kept it on the fens,
Now all I have is my tyres,
Because of those damned oxygens.

Isn't the major benefit of using nitrogen over atmospheric air is that the nitrogen will have a lot less moisture, which is the major factor in heat related pressure change.

Perhaps another line of enquiry should be "Has anyone use silica gel sachets in their tubes?'

Mustard is too hot, it was on the Zep menu
