摘要： To increase a restraining force to a belt layer and to improve the durability of the tire. A band layer of a spirally wound band-like ply includes: a first ply portion extending from a starting end located between the tire equator and one end in the tire axial direction of a belt layer to the one end in the tire axial direction of the belt layer; a second ply portion extending from the one end in the tire axial direction of the first ply portion to the other end in the tire axial direction of the belt layer; and a third ply portion extending from the other end in the tire axial direction of the second ply portion to a terminal end located between the tire equator and the other end in the tire axial direction of the second ply portion. The band-like ply is continuous from the starting end to the terminal end without interruption.
