I was present when the demo's for Tyron were first done as they brought the product to the U.S. from Great Britain, where they were used by the military.
Here's how they work. Your rim has a deep well in the center so that tires can be installed on the rim, if the well wasn't there, you couldn't slip the tire beads onto a rim. In a blowout, the tire beads, either the inner or outer can slip into that well. When it does, the tire can come off of the rim and you would be riding on the steel or aluminum rim. You often see this in high speed chases when they flatten the suspect's tires. Often, you'll see the tire lean over, flop and then come off of the rim.
How Tyron works. Once both beads are installed on the rim and it's ready to be inflated, the Tyron ring is installed. The installer has to muscle one side of the tire sidewall down toward the other and then slip the Tyron ring around the deep well that was discussed above. The ring is then tighten around that well, eliminating the ability of the tire to be removed or come off during a blowout.
When Tyron demonstrated the product for the first time in the U.S., they did it in Southern California (Los Angeles) for local fire and law enforcement. They mounted an explosive charge on the sidewall of a new car. They drove the vehicle about 35mph and blew the tire. They continued to drive the car at wild speeds with the blown tire. The tire eventually disintegrates, but the beads remain on the rim. So picture a rim with two sidewalls and no tread.
So, in a typical blowout, there is a chance that the tire could come off the rim before you get, in this situation, the motor home to a safe stop. Even if the tread comes off, you theoretically still have steering control if both sidewalls are still there versus driving on the metal or aluminum rim.
Your decision in buying these would be based on the idea, could you stop your RV before the tire comes off the rim. The referenced link above about "JimO" and his blowout does not really provide enough information to make a determination that the Tyron unit was instrumental in surviving the blowout. It's a safety product that you need to weigh the pros and cons before purchasing.
I will say that during several different demonstrations, the product did keep the sidewalls on while the passenger cars were driven recklessly and still steerable.
