A drive wheel is rotatably mounted on the frame, operatively connectable to the drive shaft of the vehicle, and has a diameter of between 65% and 100% of the OEM tire diameter. Leading and trailing idler wheel assemblies are mounted on the frame. An endless track having an inner surface is disposed around the drive wheel, the leading and trailing idler wheel assemblies. The endless track has an unsupported portion between the drive wheel and one of the leading and trailing idler wheel assemblies. The unsupported portion has a length and a center. The unsupported portion deflects a distance of between 8% and 12% of its length on application of a 25-lb. force at its center.
