One very warm day a close friend of mine set off on his heavy Harley (aren't they all!) for a day trip. The rear tyre left the house looking worn but not worn out, it came home looking the one in that picture. We put it down to very hot road surfaces and a somewhat under inflated tyre which would have led to the rubber getting to even higher temperatures. The tyre, having a low tread depth, just melted away. Not saying that's the case in the picture but it's a possibility.
