Over the following decade, the engineers worked diligently on various prototypes of the Tweel Airless Radial Tire and, in 2005, the product was finally showcased at the North American International Auto Show in Detroit Michigan on the iBOT wheelchair and Segway Concept Centaur Human Transporter. The commercial launch of the X Tweel SSL for skid steer loaders was in July 2012. It was a short seven years from prototype to commercial launch which set a record.
