"pmgia"......The Tyron band was developed in England for the military and brought over here about 15 years ago. If you look at a vehicle rim, there is a deep center section. This allows the tire to be mounted. The edge of the tire must drop into that deep center in order to be stretched over the rim. Without it, you couldn't install the tire. The Tyron band covers that deep center section, once the tire is installed and prevents the tire from coming off of the rim.
In some run flat situations, the tire can drop one bead into that center section and then roll off of the rim, leaving you driving on the rim. The Tyron band prevents the tire from coming off the rim and can actually be run until all that is left are the two sidewalls of the tire.
When Tyron first appeared on the west coast, I did the explosive demo for Tyron while the local news filmed the bands in action. I set up a blasting cap on the side wall, that blew the tire while the demonstration vehicle was doing about 70mph. The driver then drove around the parking lot like crazy, showing the tire would not come off even though it was flat. We did the demo again in Vegas and they hired someone else when they did the east coast demo.
