PROBLEM TO BE SOLVED: To provide a radial tire capable of greatly improving durability of a bead part compared to a conventional level by extremely restricting growth of cracking in the bead part. SOLUTION: This radial tire is composed of a skeleton of a carcass comprising a carcass main body comprising plies of rubber-coated cords extended in radial directions between a pair of bead cores, and a bent part comprising the plies wound around the bead core from the inside of the tire outward to be extended radially outward of the tire. Coating rubber is provided to cover at least terminal parts of the bent parts, and the coating rubber is composed of rubber composition comprising layered clay minerals in organic form blended by 1-30 pts. mass to 100 pts. mass of rubber.
