Nitrogen and regular air mix in tires?

For charging, Nitrogen is chosen over an inert... say... Argon, Helium, Neon Krypton, Xenon and Radon... because it's cheap and easy

Helium would be a poor choice for other reasons than cost. It's tiny - a helium molecule is a single atom, the second smallest atom out there. That means it more easily escapes.

(I'm too lazy to figure out if a helium molecule is smaller than hydrogen - hydrogen has the smallest atom, but is two atoms per molecule.)

When pro-Nitrofil folks start the argument about the size of gas atoms, my response is "how large is the gap between the rubber atoms?", and the conversation usually ends right there, lol! Since rubber is a porous compound, quibbling about the size of any gas atom is really pointless, but until someone actually points this out, the "argument" on paper usually goes completely unchallenged. This, folks, is why High School Chemistry teachers said chemistry was important to everyone's daily lives. It also comes in handing when you wish to avoid today's common Techno-Scams.

Also, if you over inflate the tires with helium, the bike might float away! :shock:

My my my ...I think I’ll use air ..so far it’s free thank god

So... I had a truck driver talking at me one day (I'm always surrounded by them... it's an occupational hazard I guess)...

He was telling me that my scale was wrong... like... within two minutes of it being tested, calibrated, and proven using a 25,000lb weight cart. His scle ticket said he was 80,180lbs... 180lbs more than legal.

Now, I wouldn't have done this if I thought he'd be so gullible as to totally believe it, but I knew he was the type that would be overtaken by logic soon after, so I suggested he just let 10lbs out of each tire... 18 wheels, 10 tires, that's 180lbs...

:smilie_happy:

And yes, Helium would be a terrible choice... it'd leave the tire at about the same rate it was introduced... mebbie we could market a mylar innertube? :yahoo:

I run argon/CO2 mix in my MIG, and straight argon in my TIG unit... lessee... I could unseat one side of the bead, put the thing in an enclosed tank, submerge the tire with pure propylene glycol, to delete all the air... then I could push the glycol out with argon, flip the tire, let it drain, reseat the bead, charge it with argon, wipe off all the mess, and develop a marketing strategy to make it popular at the price of oh... it'd probably take 4 hours a tire once the equipment was developed... hmmm... $300 a tire?

I've considered building an Amish motorcycle... burns diesel, steel wheels... paint it flat black, put a battery powered lamp and an SMV sign on the back... and yeah, you could point out the fact that Amish people don't ride motorcycles, but perhaps I'm only half-Amish...

How's THAT for bored, Dan? :salute:

Lol, Well...let the air out of your tires and we can all debate what you should fill them back up with! :help:
