The tire explosion cases and I’ve handled many of them; there can be defects in the layering of the rubber in the building of the tire the plies being applied inappropriately. All those things have to be analyzed by a tire design expert that can help you understand why the tire failed and that it was not the fault of the drier of the car. Those are tragic, tragic accidents and even more so when we see these huge truck tires fail when you have a multi-ton truck going down the highway at 55 to 70 miles an hour can hurt or kill the driver and other people on the roadway.
