Abstract:
A pneumatic tire comprises a carcass formed of a carcass ply extending between a pair of bead portions in a toroidal shape, and a bead core disposed in a respective one of the bead portions, the bead core comprising an axially inner core and an axially outer core respectively disposed on an axially inner side and the axially outer side of the carcass ply. The bead portion comprises an inner bead apex rubber extending radially outward from the inner core, and an outer bead apex rubber extending radially outward from the outer core. An outer apex height Ho from a bead base line to a outer end of the outer bead apex rubber is in a range of from 120% to 150% of an inner apex height Hi from the bead base line to the outer end of the inner bead apex rubber.
