Tyron Bands - FMCA RV Forums – A Community of RVers
I attended a seminar where they were discussed and a video was shown. As of March this year they were $1900 installed (2) for 22.5 inch. They reportedly prevent the blown tire from collapsing into the well created when the wheel was mfg. (to make the tire easier to install), giving you more control of your vehicle at time of the blowout.
