A pneumatic radial tire for construction vehicles comprises a radial carcass of rubberized steel cord ply, a stiffener rubber disposed on a bead core, and at least two reinforcing layers of rubberized fiber cord fabrics having different cord directions as a bead portion reinforcement. This reinforcing layer satisfies the particular height relations to the carcass ply and its turnup portion.
