ABSTRACT:
A high speed tire for heavy duty vehicles includes a carcass in a radial structure, a belt layer, tapered bead apex rubbers, side packing rubbers of small thickness, and side wall rubbers. The carcass has a main body part extending from a tread part through side wall parts to a bead core in each of two bead parts, and folding-back parts each being folded back around the bear core at each edge of the main body. Each of the bead apex rubbers extends outward in the radial direction between the main body part and the folding-back part from the bead core. Each of the side packing rubbers is disposed along the outside surface in the tire axial direction of the carcass. Each of the side wall rubbers covers the packing rubber and extends from the bead part to the side wall part so as to form the outside surface of the tire. Furthermore, the 100% modulus MP of the side packing rubber is 53 to 95 kg/cm.sup.2, the 100% modulus MA of the bead apex rubber is 78 to 120 kg/cm.sup.2, the 100% modulus MS of the side wall rubber is 14 to 50 kg/cm.sup. 2, and these 100% modulus MP, MA, MS are in the relation of MS<MP<MA.
