New Michelin bike inner tube squeezes punctures closed

New Michelin bike inner tube squeezes punctures closed: "Bicycle inner tubes that contain a small-puncture-sealing slimy liquid may not be a new development in and of themselves, but Michelin has released a product that takes the concept a step further. The company's Protek Max tube not only contains a sealant, but is designed to compress when punctured to assist the self-sealing process."
