Argon in tyres?
Having read a couple of threads about how various gases diffuse through the butyl rubber in tubes, I wonder if an inert gas would be better? Argon is fairly abundant and its atomic radius is pretty big as well, if that matters.

I prefer a mix with about 20.9 % oxygen in my tires. I hear its the best

The other two posters have it right but I still have to ask; what problem are you trying to solve?

Don't forget to put fresh air in your tires regularly!~! I ran nitrogen once in my 2wd truck. Absolutely no difference in my humble opinion.,,,,BD

Ah, FFS people, why does every thread here have to turn into stupid stuff like this?
Personally, I would never dream of using anything but a regular old pump to fill my tubes. I've never even used a CO2 thingy.
Can't you for one second think about something theoretically? Are you really that narrow in your thought processes, that you find that impossible?
View this as a question in the same vein as a question such as "Are we alone in the universe?"...

Good question. Given threads like this, there has to be more intelligent life out there somewhere.

Race cars use pure nitrogen in those tires because ambient air can have too much moisture. When that moisture boils, you can have all kinds of problems. We cyclists never deal with anything close to those kinds of speeds and cornering forces. The same can be said of our street cars.

Argon is a bit pricey to be filling bike tires. i'll stick to using my argon with my tig welder

Forget the practicalities and focus on the chemistry and physics of it.

I fill my tires with chocolate, that way when it punctures I get a delicious treat as well.

it is the concentration of these trace gases that causes the greenhouse gas problem. The trace gases are made up of Argon, Carbon Dioxide, Neon, Helium, Methane, Hydrogen, Nitrous Oxide and Ozone.
There goes my personal methane recycling idea...
I can forget about NAWS for my bike too.

It's gonna slow you down: argon has a density of 1.784 kg/m3 while air's density is 1.2 kg/m3. Think of all that extra mass to accelerate.

I thought race cars use Nitrogen because it doesn't expand from heat as much as ambient air???

Size isn't the only factor -- polarity will affect the diffusivity as well.
I think you should fill your tubes with UF6, which has a very low speed of sound. That way, everytime you braked you'd get little sonic booms in your tires.
