In a pneumatic tire, a bead core has end portions in a tire width direction formed as vertical lines along a tire radial direction. A length of the vertical lines is from 20% to 30% of a core height. In two adjacent bead core layers of first, second and third layers, the radial outer layer tire includes two or more bead cores more than the radially inner layer tire, and a misalignment amount between the bead wires each at an end portion on one side in the tire width direction is one-half of a bead wire thickness. A side on which the misalignment amount between the first and second layer bead wires is one-half of the thickness of the bead wire is opposite in the tire width direction to a side on which the misalignment amount between the second and third layer bead wires is one-half of the thickness of the bead wire.
