Measurements will be looking for swings in pressure with temperature.
This will be part of the non road test, fill the tire at night to a set pressure, lay it down on the ground where the sun will hit it, let it get good and hot to simulate being driven and check pressure again. I am not expecting much to happen.
The result I am looking for in the cooling test for the tread package to run cooler. Tread slightly cooler, side wall and rim, slightly warmer.
If the complex gasses stay in the tire longer that would be nice too, (the idea behind stayfill).

There's no reason any of those gases would pull any measurable heat out of your tires any more than the nitrogen would, and it also seems kind of irresponsible to test your theory on the road with no idea how those gases react with the tire material under heat & load, while pulling trailer loads of welding equipment. You could probably keep liquid propane in a tire, buy I doubt that you'd really want to drive around on it
Did you read the post?
There is an entire pre-onroad phase to this.

I know the gases I am going to test have been used on road or track before.
A company called stayfill sell a fluorocarbon to fill vehicle tires, likely HFC-125 (fire suppressant), R-134a, or "canned air" aka R-143.
Plus how is fire suppressant going to blow up?
You spray into a room full of fire and it goes out, if that's not a definitive test than I dont know what is.
An R-404a mixture was used in F1. Do you think if it were going to blow up they would use it?
No of course not .
