Abstract
In a pneumatic tire, a turned back portion of a carcass layer contacts a body portion of the carcass layer in a cross-sectional view in a tire meridian direction to form a closed region surrounding bead cores. A rubber occupancy ratio in the closed region is in a range of 15% or less. The bead cores have a predetermined wire arrangement structure formed by arranging wire cross sections of bead wires in the cross-sectional view in the tire meridian direction. Additionally, a self-contact height (CH) of the carcass layer and a circumferential length (L) of the wire arrangement have a relationship 1.0≤CH/L≤10.0.
