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.
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?'
