Abstract
Official abstract text for this publication.
In a tire, a ribbon rubber includes a first inclining portion which inclines with respect to a tire-circumferential direction from an outside second row of a tire-width direction toward an outside first row in a winding direction; and a first parallel portion placed parallel to the tire-circumferential direction to configure the outside first row of the tire-width direction, a winding-start end of the first parallel portion being connected to a winding-finishing end of the first inclining portion, the winding-finishing end of the first parallel portion is placed closer to the winding direction than the winding-finishing end of the first inclining portion, or is placed at the same position as the winding-finishing end.
First claim
Opening claim text (preview).
What is claimed is: 1. A tire comprising: a rubber portion formed by a ribbon rubber which is spirally wound along a tire-circumferential direction, wherein the ribbon rubber includes: a first inclining portion which inclines with respect to the tire-circumferential direction from an outside second row of a tire-width direction toward an outside first row in a winding direction; and a first parallel portion placed parallel to the tire-circumferential direction to configure the outside first row of the tire-width direction, a winding-start end of the first parallel portion being connected to a winding-finishing end of the first inclining portion, the winding-finishing end of the first parallel portion is placed at a position further in the winding direction than the winding-finishing end of the first inclining portion, or is placed at the same position as the winding-finishing end; and wherein the outside second row is sequentially adjacent the outside first row, and wherein the ribbon rubber further includes: a second inclining portion which inclines with respect to the tire-circumferential direction from the outside first row of the tire-width direction in the winding direction toward the outside second row, a winding-start end of the second inclining portion being connected to the winding-finishing end of the first parallel portion, and a second parallel portion placed parallel to the tire-circumferential direction to configure the outside second row of the tire-width direction, a winding-start end of the second parallel portion being connected to a winding-finishing end of the second inclining portion. 2. The tire according to claim 1 , wherein the ribbon rubber further includes: a third inclining portion which inclines with respect to the tire-circumferential direction from the outside second row of the tire-width direction in the winding direction toward an outside third row that is sequentially adjacent to the outside second row on a side opposite to the outside first row, a winding-start end of the third inclining portion being connected to the winding-finishing end of the second parallel portion, the winding-start end of the third inclining portion is placed at a position further in a direction opposite to the winding direction than the winding-start end of the second inclining portion, and the winding-finishing end of the third inclining portion is placed at a position further in a direction opposite to the winding direction than the winding-finishing end of the second inclining portion. 3. The tire according to claim 2 , wherein the ribbon rubber further includes: a third parallel portion placed parallel to the tire-circumferential direction to configure the outside third row of the tire-width direction, a winding-start end of the third parallel portion being connected to the winding-finishing end of the third inclining portion; and a fourth inclining portion which inclines with respect to the tire-circumferential direction from the outside third row of the tire-width direction in the winding direction toward an outside fourth row that is sequentially adjacent to the outside third row on a side opposite to the outside second row, a winding-start end of the fourth inclining portion being connected to the winding-finishing end of the third parallel portion, the winding-finishing end of the third inclining portion is placed at a position further in a direction opposite to the winding direction than the winding-start end of the second inclining portion or is placed at the same position as the winding-start end, the winding-finishing end of the third parallel portion is placed at a position further in the winding direction than the winding-finishing end of the third inclining portion, or is placed at the same position as the winding-finishing end, and the winding-finishing end of the fourth inclining portion is placed at a position further in a direction opposite to the winding direction than the winding-start end of the second inclining portion, or is placed at the same position as the winding-start end. 4. The tire according to claim 3 , wherein the winding-finishing end of the first parallel portion is placed at the same position as the winding-finishing end of the first inclining portion, the winding-finishing end of the third inclining portion is placed at a position further in a direction opposite to the winding direction than the winding-start end of the second inclining portion, and is placed at the same position as the winding-start end of the first inclining portion, the winding-finishing end of the third parallel portion is placed at the same position as the winding-finishing end of the third inclining portion, and the winding-finishing end of the fourth inclining portion is placed at the same position as the winding-start end of the second inclining portion. 5. The tire according to claim 4 , wherein all of lengths of the inclining portions in the tire-circumferential direction are the same. 6. The tire according to claim 4 , wherein all of inclination angles of the inclining portions with respect to the tire-circumferential direction are the same.
