Local manufacturing giant Michelin is opening a new plant in Piedmont to produce a new wheel / tire design called the Tweel. The Tweel made the cover of Time Magazine in 2005 and has been touted as a huge breakthrough in automotive technology. The airless design incorporates a molded tread band on a steel rim that is connected to the hub with a series of energy absorbing polyurethane spokes. Michelin has been working on a partnership with John Deer on this innovation and looks to have an impact on the commercial mowing market. The plant is located near the current Michelin plant at the SCTAC airport, formerly known as the Donaldson Center.
