Michelin has been showing off its idea of combining the wheel and tire into a single component as far back as 2005. Dubbed the Tweel, the novel design replaced standard pneumatic tires and metal wheels with deforming spokes around a hub. While uses of the Tweel are still limited, the tech is about to get a big upgrade in production with Michelin opening a dedicated factory to build them in Piedmont, SC, on November 20.
