Abstract:
A method for manufacturing a motorcycle tire includes forming a cylindrical raw tire body including a carcass body including a carcass ply and bead cores on the carcass ply, and forming a cylindrical belt ply wound in a cylindrical shape. The forming of the belt ply includes filling the tire body to expand to first expanded phase, winding a sheet-type belt ply by extending the sheet-type belt ply on bell rings to form the cylindrical belt ply with inner surface bonded to the apex of the tire body, filling the tire body to expand the apex of the tire body along with the belt ply to second expanded phase, increasing diameter of an expandable profile deck to expand the apex of the tire body along with the belt ply to third expanded phase, and winding down edges of the belt ply to bond the belt ply to the tire body.
