Abstract
In a tire, a middle land portion includes a first middle narrow groove having a linear shape or an arc shape and extending through the middle land portion and a second middle narrow groove having a Z-shape and extending through the middle land portion. A center land portion includes a first center narrow groove having one end at an edge portion of the center land portion, connected to a center main groove, and having an other end inside the center land portion and a second center narrow groove extending in a tire circumferential direction and having both ends inside the center land portion. The first center narrow groove is inclined in one direction of the tire circumferential direction from the one end toward the other end. The first and second center narrow grooves are arranged in a V-shape whose top portion is directed to the one direction.
