The carcass ply is formed by arranging unvulcanized strip pieces (11) around a surface of a toroidal core (N) which surface has a horseshoe-shaped profile, whereby the carcass ply is made up of a plurality of circumferentially arranged strip pieces. The strip pieces are each made of rubberized parallel cords (15) extending between the bead portions through the tread portion and sidewall portions. In the green tire, the strip pieces are each provided on at least one side thereof with a plurality of vent grooves (30) having a depth of 0.1 to 2.0 mm and a width of 0.1 to 3.0 mm.
