A pneumatic tire comprising: a tread having an outer surface that forms a tread surface; a pair of sidewalls that extend almost inward from ends, respectively, of the tread in a radial direction; a pair of beads disposed inward of the sidewalls, respectively, in the radial direction; and a carcass that is extended on and between one of the beads and the other of the beads along inner sides of the tread and the sidewalls, wherein each bead includes a core (16, 40), the core (16, 40) includes a non-stretchable wire wound in a circumferential direction, in a cross-section of the core (16, 40) taken at a plane perpendicular to the circumferential direction, two or more rows of cross-sections (26, 42) of the wire aligned almost in an axial direction are stacked, when, of the rows, a radially innermost row is a first row, and a row immediately outside the innermost row in the radial direction is a second row, the number of cross-sections (26, 42) of the wire in the first row is less than the number of cross-sections (26, 42) of the wire in the second row, an inner end of the second row is located axially inward of a line that is drawn from an inner end of the first row and that is perpendicular to a direction in which the first row extends, in the cross-section of the core (16, 40) taken at a plane perpendicular to the circumferential direction in a state where the tire is mounted to a normal rim, an angle (α) between a bottom side of the core (16, 40) and a bead base line, which corresponds to a line that defines a rim diameter of the normal rim on which the tire is mountable, is greater than or equal to 2°, and not greater than 9°, characterized in that when, of the cross-sections (26, 42) of the wire in the second row, an axially innermost cross-section is a reference cross-section, VL represents a tangent drawn from an axially inner end of the reference cross-section and extending in the radial direction, P1 represents an intersection point between the tangent and a radially inner surface of the carcass, and P2 represents an intersection point between the tangent and a bottom of a bead portion, a distance T between the intersection point and the intersection point is greater than or equal to 3.1 mm, and not greater than 4.0 mm. a tread having an outer surface that forms a tread surface; a pair of sidewalls that extend almost inward from ends, respectively, of the tread in a radial direction; a pair of beads disposed inward of the sidewalls, respectively, in the radial direction; and a carcass that is extended on and between one of the beads and the other of the beads along inner sides of the tread and the sidewalls, wherein each bead includes a core (16, 40), the core (16, 40) includes a non-stretchable wire wound in a circumferential direction, in a cross-section of the core (16, 40) taken at a plane perpendicular to the circumferential direction, two or more rows of cross-sections (26, 42) of the wire aligned almost in an axial direction are stacked, when, of the rows, a radially innermost row is a first row, and a row immediately outside the innermost row in the radial direction is a second row, the number of cross-sections (26, 42) of the wire in the first row is less than the number of cross-sections (26, 42) of the wire in the second row, an inner end of the second row is located axially inward of a line that is drawn from an inner end of the first row and that is perpendicular to a direction in which the first row extends, in the cross-section of the core (16, 40) taken at a plane perpendicular to the circumferential direction in a state where the tire is mounted to a normal rim, an angle (α) between a bottom side of the core (16, 40) and a bead base line, which corresponds to a line that defines a rim diameter of the normal rim on which the tire is mountable, is greater than or equal to 2°, and not greater than 9°, characterized in that when, of the cross-sections (26, 42) of the wire in the second row, an axially innermost cross-section is a reference cross-section, VL represents a tangent drawn from an axially inner end of the reference cross-section and extending in the radial direction, P1 represents an intersection point between the tangent and a radially inner surface of the carcass, and P2 represents an intersection point between the tangent and a bottom of a bead portion, a distance T between the intersection point and the intersection point is greater than or equal to 3.1 mm, and not greater than 4.0 mm.
