ABSTRACT:
A radial tire for a construction vehicle includes a tread, a pair of sidewalls extending radially inwardly and terminating in inner edges having bead cores embedded therein, a carcass made of a steel cord ply extending between the bead cores, a belt arranged between the carcass and the tread to form with the carcass a main reinforcing layer, and bead reinforcing layers. Each of the bead reinforcing layers includes at least two sets of fiber cord layers. Each of the sets has at least two fiber cord layers. The at least two sets of the fiber cord layers are arranged extending radially outwardly from the proximity of an axially outer portion of the bead core and spaced each other to have a minimum spaced distance in the proximity of the bead core and a maximum spaced distance at radially outer end between the two sets of fiber cord layers, said fiber cord layers within said sets being substantially uniformly spaced from each other.
