A pneumatic tire (22) has sipes (35) in each land portion (31) defined by wide-width grooves (30) in a tread portion (21), in which a sipe corresponding to at least a part of these sipes comprises a pair of main portions (36a, 36b) slightly shifted with respect to each other in the axial direction and a link portion (37) connecting opposed end portions of said main portions to each other, and the pair of the main portions (36a, 36b) are inclined in opposite directions with respect to the radial direction so as to make a mutual distance (L) between the main portions large. There is also provided a vulcanization mold (41) for the production of such a tire, including blades (50) for forming the sipes (35), more particularly blade main segments (53a, 53b) for forming the sipe main portions (36a, 36b) and a link segment (54) for forming the sipe link portion (37). <IMAGE> |
