Abstract: A tire having a rubber assembly including a first rubber member, a second rubber member, and a third rubber member which are arranged in series in the cross-section including the tire rotational axis. The method includes: extruding the unvulcanized rubber assembly as two separate parts which are a first extrusion rubber portion and a second extrusion rubber portion divided at a division surface passing through the unvulcanized first rubber member; winding the first extrusion rubber portion into a base annular body; and forming the unvulcanized rubber assembly by winding the second extrusion rubber portion so that only the first rubber member included in the second extrusion rubber portion overlaps with the first rubber member included in the base annular body.

Abstract: 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.
