Abstract:
A pneumatic tire 2 includes a tread 4, a pair of sidewalls 6, a pair of beads 8, and a carcass 10. In the pair of beads 8, each bead 8 includes a core 30 and a bead filler 32 extending outward from the core 30 in the radial direction. A minimal value θa of the inclination angle of the bead filler 32 is greater than or equal to 30 degrees, and is not greater than 44 degrees. A ratio Wa/Wb of a width Wa of the bead filler 32 to a width Wb of a bead portion is greater than or equal to 0.30, and is not greater than 0.45.
