Abstract
A radial tire for a heavy load having an aspect ratio of 80% or less, mountable to a standard 15.degree. tapered rim, has a pair of tire beads, each of which includes an assembly of elements which improve the durability of the bead. Each of the tire beads includes a bead core, a cord reinforced carcass ply, the carcass ply being turned up around the bead core in each tire bead from inside to outside to terminate in a radially outer edge thus forming a carcass ply main portion and a pair of carcass ply turnup portions and a steel cord reinforcing filler which has a portion which extends from the bead core both axially and radially outward thereof to terminate in a radially outer edge, and satisfying the following relationships for each of the tire beads: 7.35<(W.sub.1 /D).ltoreq.9.85 wherein W.sub.1 is a thickness of a side wall, along a line perpendicular to the carcass ply main portion, from the outer surface thereof to the radially higher one of either the outer edge of the carcass ply or the outer edge of the steel reinforcing filler, and D is the diameter of each cord of the radially higher one of the carcass ply or reinforcing filler.
