  "textContent": "A tire tread pattern includes a center land portion and an intermediate land portion on an outer side in a width direction thereof. A center land portion region includes no grooves, includes a first sipe having a wide width open to circumferential main grooves on both sides and includes a second sipe having a narrow width between adjacent first sipes and open to the circumferential main grooves on both sides. An intermediate land portion region includes an intermediate lug groove opening to a circumferential main groove in contact with the intermediate land portion. A circumferential direction distance between opening ends of the adjacent first sipes is equal to a distance between opening ends of adjacent intermediate lug grooves in which the region between at least some opening ends in the circumferential direction overlaps the region along the circumferential direction between the opening ends of the adjacent first sipes.",
