Claim 0:
1. A tire comprising:
in a surface of a tread of the tire, a land portion row in which four land portions each defined by circumferential grooves extending in a circumferential direction of the tread or by a circumferential groove and a tread edge are arranged in parallel in a width direction of the tread;
in a land portion on one end side of the land portion row, a recess that opens in the circumferential groove on an adjacent land portion side; and
an intermittent sipe extending in an orientation intersecting the width direction of the tread, intermittently by being interrupted by the circumferential groove, from a position of a start end corresponding to the recess, across three land portions of the four land portions excluding the land portion on the one end side,
wherein the intermittent sipe opens in a surface of each of the three land portions via an inclined surface from the surface of each of the three land portions toward the intermittent sipe,
wherein the recess has a substantially V-shape defined by two side walls extending away from each other from an interior of the land portion on the one end side toward the circumferential groove,
wherein each of the two side walls defining the recess includes an inclined surface from a surface of the land portion on the one end side toward a bottom portion of the circumferential groove,
wherein a maximum length of the inclined surface of the each of the two side walls in the circumferential direction of the tread is from 25% to 150% of a maximum length of the recess in the circumferential direction of the tread, and wherein a depth of the recess is similar to a depth of the circumferential groove.
