Abstract
A pneumatic radial tire for construction vehicle comprises a carcass of a radial structure comprised of at least one rubberized steel cord carcass ply body and its turnup portion, and a stiffener rubber arranged above a bead core between the carcass ply body and its turnup portion. In order to improve the bead portion durability of this tire, a cord distance between the carcass ply body and its turnup portion passes through greatest value, minimum value, maximum value and smallest value from the vicinity of the bead core outward in the radial direction of the tire and heights of the carcass ply body corresponding to the above minimum and maximum values as well as height of the turnup end measured from the base line satisfy particular relations to a flange height FH of the standard rim.
