A pneumatic radial tire having at least one carcass ply, distal ends of which are folded back axially outwardly about a pair of bead cores to form respective turn-up portions. A hard rubber sheet is disposed on the outer side of each turn-up portion in such a manner as to partially overlap with the same in a mutually spaced-apart relationship, and a soft rubber material which is softer than the hard rubber sheet is interposed between the turn-up portion and the hard rubber sheet, thereby reducing the amount of stress and heat occurring in the vicinity of the end portions of the turn-up portions of the carcass ply.
