  "textContent": "A tire (2) includes a tread portion (T) and a pair of side portions (S). An agitating portion (32) is provided on an inner part in a radial direction with respect to a position (PA) indicative of a maximum width over an external surface (34) of each of the side portions (S). The agitating portion (32) includes a large number of dimples (36) which are dented inward from the external surface. An edge of the dimple (36) has a circular contour. A ratio of a depth of the dimple (36) to an outside diameter of the dimple (36) is equal to or higher than 0.2 and is equal to or lower than 0.5. A ratio of a distance between a center of one of the dimples (36) and a center of the other dimple (36) which is close to the one of the dimples 36 to the outside diameter is equal to or higher than 1.2 and is equal to or lower than 2. It is preferable that the outside diameter of the dimple (36) should be equal to or greater than 3 mm and be equal to or smaller than 5 mm in the tire (482). It is preferable that an array pattern of the large number of dimples (36) should be an orthogonal array in the tire (2).",
