In order to suppress reduction in shock burst resistance performance of a pneumatic tire 1 and improve productivity, a belt cover layer 15 is formed by a belt cover material 40 being wound in a spiral shape, said belt cover material comprising a first cover material 41 and a second cover material 42. When one side of the tire equatorial plane CL in the tire width direction is a first side S1 and the other side is a second side S2: the first cover material 41 is arranged from a position between the shoulder area Ash on the second side S2 and the tire equatorial plane CL, to the shoulder area Ash on the first side S1; the second cover material 42 is arranged from a position between the shoulder area Ash on the first side S1 and the tire equatorial plane CL, to the shoulder area Ash on the second side S2; the first cover material 41 and the second cover material 42 have an overlapping section 45 at a position that is the same for both in the tire width direction; and the overlapping section 45 has a width in the tire width direction that fluctuates depending on the position in the tire circumferential direction.

    为了抑制充气轮胎(1)的耐冲击破裂性能的降低并且提高生产率,带束覆盖层(15)通过将具有第一覆盖件(41)和第二覆盖件(42)的带束覆盖件(40)卷成螺旋状而形成,在将轮胎宽度方向上的比轮胎赤道面(CL)靠一方侧设为第一侧(S1),将另一方侧设为第二侧(S2)的情况下,第一覆盖件(41)从第二侧(S2)的胎肩区域(Ash)与轮胎赤道面(CL)之间的位置配设至第一侧(S1)的胎肩区域(Ash),第二覆盖件(42)从第一侧(S1)的胎肩区域(Ash)与轮胎赤道面(CL)之间的位置配设至第二侧(S2)的胎肩区域(Ash),第一覆盖件(41)和第二覆盖件(42)在轮胎宽度方向上的位置成为相互相同的位置的位置处具有重叠部(45),重叠部(45)的轮胎宽度方向上的宽度根据轮胎周向上的位置而发生变动。
