Abstract
A tireincludes beads, a carcass, and an insert. The carcassincludes a carcass ply. An inner partof each beadincludes an inner coreand an inner apexthat extends almost outward of the inner corein the radial direction. An outer partof each beadincludes an outer coreand an outer apexthat extends almost outward of the outer corein the radial direction. A ratio of a complex elastic modulus Ea of the inner apexto a complex elastic modulus Eb of the outer apexis less than or equal to 0.3. A ratio of the complex elastic modulus Ea to a complex elastic modulus Ec of the insertis greater than or equal to 1.
