Abstract:
1. A non-pneumatic tire for supporting an applied load comprising: a generally annular inner surface that engages a hub having an axis of rotation, a generally annular outer ring, an interconnected web between said generally annular inner surface and said generally annular outer ring comprising at least two radially adjacent layers of elements at every radial cross-section of said tire defining a plurality of generally polygonal openings, the interconnected web including a plurality of tangential web elements that are generally aligned with a tangent to a circle centered about the axis of rotation; said generally annular outer ring and said interconnected web being deformable when said tire is subjected to said applied load; wherein a plurality of said web elements are angled relative to a plane containing said axis of rotation to facilitate buckling of said web elements, wherein, when the applied load is applied, web elements in a region above the axis of rotation are subjected to a tensile force while web elements in a region between the applied load and a footprint region are subjected to a smaller portion of the applied load as compared to the remaining portions of the web elements.
