Abstract: A traction system (10) is presented comprising a wheel structure (12), defining a substantially circular circumference,- and a closed-loop member (14) carried by and engaged with the wheel structure. The closed loop member is operable for expanding its circumference between a substantially circular geometry and various non-circular geometries while remaining engaged with the wheel structure.
