This is a picture of one of my failed chinese tires. 
OK you did it again with this picture. The natural tendency of a human when presented a picture is to look at the center. When you look at the center of this picture, you see a tire with some rocks stuck in the tread. So what. Despite making this comment about this picture about a year ago . . . well just let me help the readers who fell into the same trap as I and are saying "so what". Look at the top of the picture. You can see across the edge of the tread with the wood in the background. Normally, the tread would be either perfectly flat across it (from one side of the tire to the other) or slightly curved with the center of the tire being slightly larger in diameter than the portions near the sidewalls. But you can see in this picture that the diameter of the tire toward the sidewall that is not in contact with the wood is significantly larger than the diameter toward the sidewall that is in contact with the wood.
I'm thinking our engineers will be able to tell us exactly what is going on inside this tire and the nature of the impending failure that was avoided by removing this tire from service.
