Non-pneumatic tire

A non-pneumatic tire comprising:

• an annular outer ring;
• an annular inner ring provided in concentric fashion toward the interior in a tire radial direction from the outer ring;
• a plurality of spokes that connect the outer ring and the inner ring, and that are provided in respectively independent fashion in a tire circumferential direction;
• and
• an annular tread that is arranged toward the exterior in the tire radial direction from the outer ring and that forms a contact patch, wherein
• the plurality of spokes each comprises a joint that is joined to an inner circumferential surface of the outer ring,
• a long direction of the joint makes an angle of less than 90° with a tire width direction,
• the outer ring comprises a laminate having a plurality of fiber layers, and at least one elastomer layer interposed between an adjacent pair of the plurality of fiber layers,
• the plurality of fiber layers include an outermost layer which among the plurality of fibers is that which is arranged in outwardmost fashion in the tire radial direction, and an innermost layer which among the plurality of fibers is that which is arranged in inwardmost fashion in the tire radial direction,
• at least one of the outermost layer and the innermost layer contains a first fiber array at which fibrous material is arrayed so as to extend in the long direction of the joint,
• the first fiber array is one of two thereof that are respectively provided such that there is one thereof at each the outermost layer and the innermost layer, and
• the outermost layer and the innermost layer each further comprises, in addition to one of the two first fiber arrays, a second fiber array at which fibrous material is arrayed so as to extend in the tire circumferential direction.

• the first joint and the second joint are arranged in alternating fashion along the tire circumferential direction, and
• a way in which a long direction of the first joint is inclined with respect to the tire width direction is at least one of a) identical to a way in which a long direction of the second joint is inclined with respect to the tire width direction, with the fibrous material of the first fiber array extending in the long direction of the first and second joints, and b) opposite a way in which the long direction of the second joint is inclined with respect to the tire width direction, with the first fiber array having a first-side fiber array at which fibrous material is arrayed so as to extend in the long direction of the first joint and a second-side fiber array at which fibrous material is arrayed so as to extend in the long direction of the second joint.
