Abstract:
A pneumatic tire includes a tread, sidewalls, clinches, beads, a carcass, and strips. Each bead includes a core, a first apex and a second apex, the carcass includes a carcass ply which is turned up around the core from the axially inner side toward outer side such that the carcass ply is divided into a main portion and a turn-up portion, each strip has radially inner edge positioned between the main and turn-up portions, the second apex is positioned between the turn-up portion and each clinch, each strip has outer edge positioned to correspond to or on inner side of a point of maximum width of the tire in radial direction, the second apex has outer edge positioned on radially inner side of the outer edge of each strip, and the second apex includes crosslinked rubber and has complex elastic modulus in range of from 60 MPa to 70 MPa.
