A radial tire having carcass plies of polyester cords in which all or part of carcass plies are folded from the inside of bead core to the outside and a steel chafer outside the folded edges or a reinforcing layer of organic fiber. The steel chafer has a cord angle of 15 DEG -45 DEG , and a height H equal to 15-28% of the tire internal height IH. The maximum height h of the folded edges of the carcass plies is at most 85% of the height H of the steel chafer and the cord angle of the organic fiber reinforcing layer is 20 DEG -75 DEG with respect to the tire circumferential direction and 10 DEG or more with the cords in the steel chafer. |
