A non-pneumatic tire (24) includes an inner circumferential barrier (26), an outer circumferential barrier (28) radially spaced from the inner circumferential barrier, and a support structure (32) extending between the inner and outer circumferential barriers. The support structure includes a plurality of first ribs (34) extending between the inner and outer circumferential barriers. The first ribs have a cross-section substantially perpendicular to an axial direction of the tire, with the cross-section having a first curvilinear shape, wherein the first curvilinear shape is a curve having either a single direction of curvature or a direction of curvature that changes once. The support structure also includes a plurality of second ribs (36) extending between the inner and outer circumferential barriers. At least some of the first ribs intersect at least some of the second ribs such that intersecting first ribs and second ribs share common material at points of intersection. |
