Abstract
A pneumatic tire has bead cores provided in bead portions. The bead cores include a first bead wire, and a second bead wire having an elongation α, where α(%)=ΔL/L×100, L is a length of each of the bead wires under no load, and ΔL is an elongation amount obtained when a unit load is applied. The elongation α of the second bead wire is greater than an elongation of the first bead wire. The number of the second bead wire provided in an innermost side portion in a tire radial direction is at least one.
