The tire comprise a rubber assembly 15 including a first rubber member 11, a second rubber member 12, and a third rubber member 13 which are arranged in series in the cross-section including the tire rotational axis. The method comprises the steps of: extruding the unvulcanized rubber assembly 15 as two separate parts which are a first extrusion rubber portion 16 and s second extrusion rubber portion 17 divided at a division surface passing through the unvulcanized first rubber member 11; winding the first extrusion rubber portion 16 into a base annular body 20; and forming the unvulcanized rubber assembly 8 by winding the second extrusion rubber portion 17 so that only the first rubber member 11 included in the second extrusion rubber portion 17 overlaps with the first rubber member 11 included in the base annular body 20.
A method for manufacturing a tire comprising a rubber assembly of a first rubber member made of a first rubber composition, a second rubber member made of a second rubber composition different from the first rubber composition, and a third rubber member made of a third rubber composition different from the first rubber composition, wherein in a cross-section of the tire including the rotational axis of the tire, the rubber assembly extends in a direction, the second rubber member is connected to a first end portion of the first rubber member in said direction, and the third rubber member is connected to a second end portion of the first rubber member in said direction, the method comprising:
