PROBLEM TO BE SOLVED: To provide a pneumatic radial tire which is considerably improved in comfortableness against vibration in addition to retaining control stability at a high level. SOLUTION: This pneumatic radial tire comprises a pair of bead parts 1, a pair of side wall parts 2, and a tread part 3 troidally extending between both side wall parts 2, and is provided with a radial carcass 5 which reinforces each of these part over between a pair of bead cores buried in the bead parts 1, a belt 6 which strengthened the tread part 3 around an outer circumference of a crown part of a carcass layer. A carcass has a folding part which is folded from the inside to the outside of the tire around each bead core. The tire also provided with a bead filler rubber 7 taperingly extending from the bead core toward the tread part 3 between the folding part and the carcass. The tire is placed an integral composite member 8 composed of plain cloth and rubber where fibers made of a steel are crossingly arranged each other to be reticulate shape at the side wall part.
