First claim
Opening claim text (preview).
What is claimed is: 1. A tire, comprising: a hub; and a spoke that extends from the hub in a radial direction of the tire, wherein the spoke has a first face and a second face that are spaced from one another in a longitudinal direction of the tire, wherein the spoke has a crack suppression feature that has a groove that extends into the first face, wherein the groove has a length extending in the radial direction and a width shorter than the length extending perpendicular to the length, wherein the groove extends in the radial direction wherein the groove is one of a plurality of first grooves of the crack suppression feature that extend into the first face and are spaced from one another in an axial direction of the tire, wherein the plurality of first grooves extend in the radial direction; and wherein the crack suppression feature has a plurality of second grooves that extend into the second face, wherein the plurality of second grooves extend in the radial direction, wherein the first face and the second face are oppositely disposed to one another in the longitudinal direction wherein a plurality of first ribs are located at the first face, wherein successive ones of the first ribs are located between successive ones of the plurality of first grooves in the axial direction, wherein the plurality of first ribs and the plurality of first grooves are shaped such that the first face has a sinusoidal shape in the axial direction; and wherein a plurality of second ribs are located at the second face, wherein successive ones of the second ribs are located between successive ones of the plurality of second grooves in the axial direction, wherein the plurality of second ribs and the plurality of second grooves are shaped such that the second face has a sinusoidal shape in the axial direction. 2. The tire as set forth in claim 1 , wherein the spoke extends from the hub in the longitudinal direction, and wherein the groove extends in the longitudinal direction. 3. The tire as set forth in claim 1 , wherein the groove extends across an entire radial length of the spoke, wherein the groove is semi-circular in cross-sectional shape.
