Abstract: A pre-strained non-pneumatic tire has an inner ring, an outer ring, and a plurality of polymeric connecting elements extending from the inner ring to the outer ring. The pre-strained non-pneumatic tire made by a process that includes forming an initial non-pneumatic tire and straining at least a portion of one of the plurality of polymeric connecting elements.

Abstract: A non-pneumatic tire includes a generally annular inner ring that attaches to a wheel, a generally annular outer ring, and an interconnected web between the generally annular inner ring and the generally annular outer ring. The interconnected web defines a plurality of openings circumferentially spaced around the tire and radially spaced at varying distances from an axis of rotation, so as to support a load by working in tension. The interconnected web includes a plurality of web elements having a varying thickness, including a first plurality of web elements above the axis of rotation and a second plurality of web elements below the axis of rotation. The varying thickness is configured to facilitate buckling of the interconnected web. When a load is applied, the first plurality of web elements are subjected to a tensile force while the second plurality of web elements buckle.

Abstract: A non-pneumatic tire includes a plurality of axially adjacent wheel portions. Each wheel portion has an inner ring, an outer ring, and a flexible, interconnected web extending between the inner ring and the outer ring. The flexible, interconnected web includes a plurality of web sectors disposed circumferentially about the tire to form a generally annular web. Each of the plurality of web sectors is hingedly connected to a pair of oppositely adjacent web sectors.
