Nitrogen in tyres/tires

[Edwin Ek]

Hi All
While down at the tyre/tire fitters today, I asked more about the 'Nitrogen' that they use and was shown the unit that removes All of the moisture content from the air prior to use. But does this make it pure Nitrogen? Matthew mentioned that Air is 78% Nitrogen but what about that remaining 22% of 'Dehumidified' Air ?

Air is 78% nitrogen, 21% oxygen, and the remaining 1% a mix of other gases. Water vapor is a separate concept.

Emil,

It might be genuine German air/water, very authentic.

Maybe some Chas Dinkelaker pale?
