This happen to us going to Albuquerque couple years ago, running about 75 mph bad vibration, made it to the car show, was backing up to park and the wife said, look at that tire, right rear, it had separated the belt was showing.

Put the spare on still had some vibration made it home slow.

In checking we had three bad tires. Someone was looking out for us!!!!!

Now I put the old Bird on jack stands when not in use.

I was told the concert is what causes tires to separate, they also said to park on plywood will help.
