Since immediate catastrophic failure has been ruled out it may be time to start limited on road testing, where 1 tire is filled with the mystery gas and the other 3 regular air.
So far my test tires have been with 2 brand new yokohama 30 inch load range C highway tires, that I purged and filled with CO2 and then took one tire forward with the R-404a test. These tires have been on rims and filled with air for a few months before I started messing with their inflation media.

I would also like to know whats going to happen this winter to these tires. Unfortunately I do not have a time machine. But a refrigerator and small trailer tire small enough to fit in said refrigerator should work in place of a time machine.

To be environmental friendly, save the O-zone (*cough* BS *cough*) and be cheap I have set aside an old empty R-134a tank that I can pump down to a vacuum and recover my tire gas. Soon I will have a compressor I can use to pull tire gas out of a tire and force in to a bottle. Then I have more tanks I can store gas in once the compressor is up and running, I dont think these other tanks will survive pulling a vacuum inside them.

The helium biasply trailer tire test will be soon. This test will just be to see how fast it leaks out.
