Redbullet, I had been researching the Conti Supersonic tubes some time ago. They've been used extensively all over the world. Came across a number of reviews on various websites where people had blowouts from the tube failing catastrophically. If I recall correctly, most of these failures involved the tube failing with a linear failure (along the circumference). No road hazards involved, just tube failure, presumably due to the extremely thin material. This would result in the type of incident you referred to in your original post.
