Argon has poor compability with Buna-N, Nitrile, and NRBT rubber. A Buna-N tire inner tube will fail prematurely when used with Argon!
As such, I retract my previous post and warn against using Argon in bicycle tires!
I looked at the tables, and to be honest, I don't understand exactly what the manufacturer meant by the "Compatibility Charts". Does "2-MODERATE TO SEVERE" mean that Argon will damage the tube or that it will easily leak (permeate through the wall, actually) out? The former seems implausible, as Argon is inert as a dead stubborn donkey.
