A pneumatic radial tire includes a bead filler, a carcass ply, a steel protection layer, and an organic fiber protection layer. A reinforcing rubber sandwiches a wind-up end of the steel protection layer. A relationship of 1≤A/B≤2 is satisfied between a width A from the wind-up end of the steel protection layer to a tire inner surface, and a width B from the wind-up end of the steel protection layer to a tire outer surface. The wind-up end of the carcass ply is covered with a ply cover member. A relationship of 0.8≤D/C≤1.2 is satisfied between a thickness C of a second bead filler positioning between the ply cover member and a first bead filler, and a thickness D of the reinforcing rubber positioning between the ply cover member and the steel protection layer.
