  "textContent": "A pneumatic tire (10) has a central land region (CT1) partitioned by a pair of circumferential direction main grooves (71, 72) extending in a tire circumferential direction. In the central land region (CT1), a block row (30) partitioned by one or a plurality of circumferential direction narrow grooves (61, 62) having a groove width narrower than the circumferential direction main groove (71, 72) is provided. The block row (30) has a land block partitioned by a width direction groove extending in a tire width direction. The width direction groove includes a width direction groove portion and a bent portion continuous to the width direction groove portion and bent in the tire circumferential direction. The groove width of the bent portion along the tire width direction becomes narrower as the bent portion advances along the tire circumferential direction.",
