"The new Michelin VISION concept is a 3D-printed, airless, wheel-tire combination composed of organic, biodegradable materials, including orange zest, bamboo, molasses, wood, and natural rubber. Instead of a runner inner tube that maintains its structure with regular injections of air, the VISION is more solid, sponge-like structure–picture a 3D spiderweb, molded into the shape of a wheel."
