Abstract
In a tire, each of sidewallsincludes a first layerdisposed axially outward of a corresponding one of beads, and a second layerextending outward from the first layerin a radial direction. When Pc represents a position of an axially outer end of an interface between a carcassand the sidewall, an outer endof the first layeris disposed radially inward of the position Pc. A hardness Hof the first layeris greater than a hardness Hof the second layer. A ratio (H/H) of the hardness Hto the hardness His preferably not less than 0.70 and preferably not greater than 0.95.
