#1 Pryolysis is the process of the tire-rubber being overheated and emitting explosive gasses. Not "warm to the touch." It has to be much hotter. Most pryo-tire explosion investigations have found tire rubber that had gotten so hot it had almost caught fire from a torch or welder. The misleading issue is - often the tire on the outside does not feel hot, so the hot-spot internally goes un-noticed.
#2 That explosive gas has to be trapped inside the tire.
#3 If there is enough heat present, a blast of oxygen has to hit it allow an explosion to take place - not much different than how a diesel engine works with a glow-plug.
#4. If there is NO heat anymore, nothing can happen without an external source of heat to ignite the mix. Thus my mention of a cigarette.
As to the story with the guy with the tire on his lap? Sounds like a normal blow-out to me - but no real facts are provided. If the tire had been over-inflated, it certainly could kill somebody at close range. I was in a shop where a guy got killed when he filled a tire - to what we think was 180 PSI. That was a "blow-out" and not a "tire-explosion." A blow-out only has the force of the PSI involved. A tire-explosion has igniting gasses involved and can easily exceed 1000 PSI.
The Bridgestone video, nor any other video has much use unless all the facts are provide. I've read many full-scale investigative reports of pyro-tire explosions.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
