  "textContent": "A motorcycle tire has a tread portion. The tread portion has a ground contact surface curved in an arc shape convex outward in a tire radial direction. The ground contact surface includes a central region and a first outer region. The ground contact surface has oblique grooves each including a portion inclined with respect to a tire circumferential direction. Each of the oblique grooves extends across the central region and the first outer region. Each of the oblique grooves includes a vertical groove portion extending at an angle α of 20 degrees or less with respect to the tire circumferential direction. A minimum distance in a tire axial direction along the ground contact surface between the vertical groove portion and an outer edge of the central region is 30% or less of a maximum width in the tire axial direction of the central region along the ground contact surface.",
