摘要： The invention can firmly fix both ends of a carcass ply while maintaining a weight saving and an effect of inhibiting a bead damage high. A pneumatic tire is provided with a bead core (5) constituted by core separated pieces (20U, 20L) separated into upper and lower sides in a radial direction, a bead apex rubber (8) extending from an upper surface thereof to an upper side in the radial direction., and a carcass ply (6A) having a ply lock portion (11) locked to the bead core (5). The ply lock portion (11) is provided with an apex and core horizontal ply portion (31) pinched between the bead core (5) and the bead apex rubber (8), or a core lower ply portion (32) extending along a lower surface of the lower core separated piece (20L), or a lower middle vertical ply portion (33Lm) pinched between separated portions (20Li, 20Lo) formed by separating the lower core separated piece (20L) into inner and outer portions in a tire axial direction, in addition to a separated piece horizontal ply portion (30) pinched between the core separated pieces (20U, 20L).

摘要： A pneumatic tire comprises the following belt (A) or belt (B). The belt (A) comprises a ply made of waved monofilament steel cords and a ply made of multi-filament steel cords, wherein the waved monofilament steel cord is (1) spirally waved so that the wave pitches PA are in a range of from 14 to 50 mm and the amplitude HA of each wave is in a range of from 0.002 to 0.02 times the pitch PA of the wave, or (2) two-dimensionally waved so that the wave pitches PB are in a range of from 5 to 50 mm, and the amplitude HB of each wave is in a range of from 0.002 to 0.05 times the pitch PB of the wave. The belt (B) comprises two plies made of waved monofilament steel cords, wherein the waved monofilament steel cord is waved so that the wave pitches P are in a range of from 0.008 to 0.08 times the circumference of the tire and the wave height of each wave is in a range of from 0.002 to 0.025 times the pitch P of the wave.
