Abstract: <P>PROBLEM TO BE SOLVED: To effectively suppress the breakage of a reinforcement element 33 at the lateral both outer ends of a reinforcement ply 32.  <P>SOLUTION: The lateral center part of a belt reinforcement layer 31 is formed in a high rigid area M where the circumferential rigidity per unit width is higher than the others. Therefore, the neutral axis of bending in and around the high rigidity area M is displaced to the radial inner side (belt reinforcement layer 31 side). Since the distances between the lateral outer ends of the belt reinforcement layer 31 (reinforced ply 32) and the neutral axis of bending are reduced, large circumferential elongations occurring at the lateral both outer ends of the reinforced ply 32 can be suppressed by the deformation of a tread part 15 in a flat shape due to ground contact.  <P>COPYRIGHT: (C)2009,JPO&INPIT
