Anyone use Tyron bands?

I just had a blowout Saturday on the rear of my coach. The tire came apart as a result of tread separation. The bead stayed on both sides of the rim. The rest of the tire was gone. I do not have Tyron bands or anything else to keep the tire on the rim. It just normally stays there. Only once have I ever had the tire come off the rim, and that did not happen until the vehicle was nearly stopped. That was an oddball 16.5 rim, which has no lip to keep the tire in place. Normal rims have a lip, so the sidewall stays in place, even under catastrophic failure.

Had them for about 6 years on our coach - when we bought new tires this year I threw them away. Unless you have all the correct tools they are almost impossible to remove to replace the tire. Tyron offers the right tools, but very few tire places will have them, and the tire guy who comes to you on the side of the road most likely doesn't have them. So, unless you have the tools, don't count on roadside assistance being any help.

When we bought our coach the dealer had them installed and he gave us the tool that allows you to loosen the band to remove it from the wheel, but we did not get the tool that is even more important: it compressed the tire away from the rim so the the band can be pulled out of the tire - without that tool it's almost impossible to get the other tool into the tire to loosen the band, and then the band gets distorted when it's yanked out around the bead. It took out tire guy almost an hour to get one tire dismounted, and he had the help of 2 other burly tire guys. I would hate to see what would have happened if I was on the shoulder of a freeway at the time...

We use them, and have for approx 3 years with no issues. The only issue is when we have the tires rotated. The tire repair guy hates them!
