Nitrogen instead of air

[rangerreece]

Lets not forget the NAS museum there. And down the road, the USAF Armaments museum in Eglin.

Been to both multiple times. Other than the traffic... Love me some P'cola

So, do both or either of these places provide Nitrogen for tires? Just wondering!

Yes. About &0% as I recall. Paul you so funny.

Found a discount nitrogen station

We are lucky in my area. We have a local store where you can get a Nitrogen "fill" fairly cheap. They have a "different" process. They actually over fill any tire with air by 21%. Than they remove the 21% oxygen part, pretty much leaving 100% nitrogen. That simple. It saves on their limited nitrogen supply and at the same time aids in reoxygenifying the earth's atmosphere. I questioned them closely about remaining 0.9% argon and 0.03% carbon dioxide, but they quickly pointed out my dysfunctional fuel strip, which made me forget about getting an answer on argon and carbon. Good people they are...even let ya pay your nitrogen bill out over 12 months if ya want.

In the April BMWON Wes Fleming reopens the nitrogen question (p. 42). He talked about air leaking out of tires. He said the nitrogen stays behind so it implies that repeatedly replacing leaked air will eventually lead to the tire being filled almost completely with nitrogen. The question is how long does it take before the tires are almost completely filled with free nitrogen?

Curious

I'm not very good at math but I did some careful calculations related to the atomic size of O2 and N, and the possibility of variations for the porosity of synthetic rubber compounds using speculative parameters available on the internet. The results varied, depending on the source of inflation, the size of any punctures, the size of the tire, and what rubber compound the tire was built using. The result was anywhere from 19 minutes to 24 years. I certainly can't refine those calculations any further but maybe a real scientist can. YMMV

Nitrogen in tires?

I can sell those same guys a canoe in the Sahara desert.

Been all over the place using plain old air.

Thanks Paul, Love the answer!

In the April BMWON Wes Fleming reopens the nitrogen question....

But WHY? Has this question/discussion not already consumed enough band width? Is Wes running out of stuff to write about? Is it an April Fool's joke?

Actually the title of the article is Nitrogen is out, Radon is in: improving motorcycle performance with noble gasses. I think Wes has been reading too much Jack Riepe.

Oh. Well then.....

I'm all for Radon. I particularly like its radioactive properties. Tends to keep Nosey Parkers and small children from getting their grimey fingers on my bike.

Nitrogen

Instead of putting nitrogen in tires with some help from my friends I put it into corn! Doing a little bit of math put about 8.5 tons into 16,320 bushels of corn. ( mucho ethanol)

 

[MCMXCIVRS]

I can't believe I'm the only one who has figured out that using pure helium in your tires reduces unsprung weight and the overall weight of your bike. It's given me serious advantages in all sorts of conditions but does slightly reduce available traction due to the tire float effect.

 

[oldandslow]

Yeah Ed it just seems to float over the mud holes.

This thread is ahead of its time. I'm thinking tomorrow should be good, though.
