Claims11
A non-pneumatic tire defining axial, radial, and circumferential directions, the non-pneumatic tire comprising:
- an annular shear band including
- an annular shear layer comprising an elastomeric material;
- and
- a plurality of discrete, annular reinforcing elements positioned within the shear layer along a plurality of axially-extending rows within a radial plane of the tire, the reinforcing elements having rectangular cross-sections along the radial plane of the tire, the reinforcing elements defining centers, wherein the centers of the reinforcing elements of adjacent axially-extending rows are offset from each other along the radial direction while the centers of the reinforcing elements of alternating rows along the radial direction are aligned with each other along the radial direction, wherein the reinforcing elements are non-metallic, and wherein a volume fraction VF of the reinforcement elements is greater than, or equal to 0.7.
