Nitrogen inflation

I've heard a lot about this, but only in reference to car tyres; has anyone
done this with their bike? Is it worth it?

Thanks
J.

 

nah. its not worth it.

its soooo two weeks ago

 

I put 80% pure Nitrogen in my tyres...works well for me

It helps prevent the bends when you resurface.

Of course, that's just the license fee ... you'll have to arrange
to put it into the tyres yourself.

yes, I use 80% nitrogen in my tires too, in fact i have a nitrogen
pressuriser suitable for inflating motorcycle tires, yours for the low low
price of $400

Someone let James Galloway at loose on an internet
connection and the result was:

Nothing; just kinda sits there (it's inert!).

This started a huge thread two weeks ago. The gist was that there were lots
of opinions but no one convinced me it was worth the cost and inconvenience.
Give it a go for a while if you want, but I reckon just making sure you
constantly have the right pressure in your tyres is much more important.

 

Actually nitrogen is the main cause of the bends when you resurface,
the benefit is it gets you 'drunk' whilst down due to Nitrogen
Narcosis - and no handover!

You're right; it was helium I was thinking of.

Nitrogen is used to inflate aviation tyres for two reasons:
Primimary reason is to eliminate a chemical reaction between the gas
used to inflate the tyre and the inner tyre linning i.e. prevent
explosion and combustion --- remember aviation tyres are subjected to
huge stresses on landing (accelerate from 0 to the plane's speed in a
split second and huge weight loadings). Aviation tyres may be
inflated with a max of 5% oxygen under the aviation regulations (this
does not apply to all planes such as ultralites etc.).

Secondary reason is the use of dry nitrogen has a very low moiture
content and without oxygen present the risk of oxidation damage to the
interior of the tyre is reduced.

The value of using pure nitrogen for a bike's tyres IMHO is bugger all
-- stick the 80/20 nitrogen/oxygen gas mix readily available at every
petrol station and check your tyre pressures every time you full up or
ride.

Cheers,
Conrad

I have always wondered why they don't spin the tyres up before
touchdown. Surely you would only need to put a couple of small vanes
on the wheels.

Is that why they call it dry?

Doctor Karl said that there's a danger that lumps of ice could form inside
the tyres and cause damage when the tyres spin-up on landing too.

OK smarty; then why is dry beer just as wet? (and don't even talk to me
about dry ginger-ale!)

You're just going out of your way to be wrong so that you can then post 'I was
wrong and I admit it' messages.

Much the same as some of the 'dry' humor found here - really very wet
verbal diarrhea

Dry simply means the gas has been scrubbed(why the process is called
scrubbed and not towelled or blowdryed we will never know) - but even
dry nitrogen gas has some albeit small moisture content. Air for
SCUBA tanks is also scrubbed so you don't end up with both an air and
fresh water supply whilst underwater.

Now if we used helium in the tires -- wouldn't that constitute a
weight reduction modification, hence a true performance mod? But if
it prevents the bends - well then that just isn't very much fun :-(

But the upside again is if you wanted to sound funny you could always
inhale a little of the gas and impersonate Donald Duck - always funny
when the effects of Nitrogen Narcosis are been exhibited!

I used to go out with a scrubber. She never told me what she did for a
living, but now I know.
