PROBLEM TO BE SOLVED: To provide a tire which has a side portion having a good appearance for a long period, and has a bead portion of improved durability. SOLUTION: The tire has a pair of the bead portions 1, a pair of the side portions 2, and a tread portion 3 ranging to both side portions 2. The tire is also provided with a carcass 4 extending in a toroid shape between the pair of the bead portions 1 and reinforcing those portions. On at least outer surfaces of the side portions 2, outermost layer side rubber members 5 are disposed. Between the outermost layer side rubber member 5 and the carcass 4, from an end portion on the outside in a tire diametrical direction of a bead core 6 buried in the bead portion 1 toward the outside in the tire diametrical direction, an inside rubber member 7 is arranged in at least a part of an area of 0-50% of the section height of the tire. The content of an antioxidant in a rubber composition used for the inside rubber member 7, is more than the content of an antioxidant in a rubber composition used for the outermost layer side rubber member 5.
