73:. At the time, Cron said that work on the Tweel began informally, starting with the idea that the load of the vehicle should be carried in the tire structure by means of tension, as happens in a traditional pneumatic tire. After realizing that cord tension carried via the sidewall would not work with zero inflation pressure, a successful experiment with polyurethane spokes lead to the basic Tweel design.

He began work on airless tire technology as early as 1997, with work on the Tweel occurring over the period 2000-2009. Although other airless tire concepts have been studied or attempted in the past, none has achieved the commercial success of the Tweel, which is based on the framework and approach
