Nitrogen filled tyres?

Now there's a coincidence, that' s what I use too..:)))))...oldbaz.

I use a 82/18 blend! You guys obviously live at sea level! :) Michael

Or get some more cynical viewpoints here:

I just*** hate*** those adiabatic changes.

Those b%@@&y adiabats are always changing things.

I have to agree. I just went up and down this thread and I am positive that not many seem to go off the beaten track. I ma fairly sure that you wouldn't get any nitrogen to fill the flat from Maree, Bridsville, Finke or even Oodnadatta. Do you all seem to stay on the bitumen?

I wouldn't touch it with a barge poll. Absolutely none where we (and the club) go. Even had an issue with a bloke with LPG. On a club trip, came across a road closed and had to do a 238 Km detour because he didn't have enough LPG to get home the detour way.

Not for us thanks.

at last some common sense,, agree complete waste of time for users who are constantly changing pressures for surfaces. but if you insist I can also sell you rocking horse **** for the garden. :-)

I have some gnomes. That's pronounced with a "GGG" a break and then "nomes".

Thanks for the offer.

Dunno about cooling on landing. Mostly used because it's dry (free of moisture, which can freeze in flight, creating an imbalance). It's also inert.

It's also abundant on the ramp. Engineers use it to charge the various gas struts and pre-charge accumulators as well. That makes it 1 less item to drag around on the ramp by having to provide compressed air.

Save your money :)

There are a few reasons that (mostly commercial) aircraft use nitrogen.
1. It does not react volumetrically to changing air pressure due to altitude as much as plain air filled tyres, this prevents expansive blowouts at altitude, malformation of the tyre due to expansion, and auto deflation due to the tyre being expanded off the rim.
2. Nitrogen is a natural fire suppressant which is a necessity to prevent a tyre fire on landing if something goes wrong. Many lower altitude aircraft are only required to have nitrogen filled tyres on the braked wheels for this reason.
3. Nitrogen, being inert, does not react with either the wheel or the tyre material.
4. Filling with nitrogen from a bottle prevents the inadvertent use of locally compressed air which will likely contain moisture. Under extreme landing conditions such as a dragging brake, the tyre can heat to a point that the moisture turns to steam, thus expanding the tyre destructively.
Air that has been satisfactorily dried will not freeze at altitude or turn to steam on landing, so moisture content alone is not a valid reason for the use of nitrogen in place of air.

Brian,
Not being a smartrrse, but there is some misinformation in your post.

Are you in the industry? ;)
