Zusammenfassung:This tire comprises: one or more circumferential belt layers T06b; and a pair of crossing belt layers T06c that are disposed adjacently to the circumferential belt layers. When the longitudinal rigidity of a cord of the circumferential belt layers is denoted by ELb, the number of the circumferential belt layers is denoted by Nb, the longitudinal rigidity of a cord of the innermost one of the pair of crossing belt layers that is located at the innermost side in the tire radial direction is denoted by ELc1, the angle of the cord of the innermost crossing belt layer relative to the tire circumferential direction is denoted by θ1, the longitudinal rigidity of a cord of the outermost one of the pair of crossing belt layers that is located at the outermost side in the tire radial direction is denoted by ELc2, and the acute-side angle of the cord of the outermost crossing belt layer relative to the tire circumferential direction is denoted by θ2, formula (1) of ELb×Nb/(ELc1×cos4θ1+ELc2×cos4θ2)
