摘要

A pneumatic tire comprises a carcass of at least one ply (1) of rubberised metallic cord fabric having its end portions wrapped radially around bead cores (3) to form respective turnups (2). An annular apex strip (5) is disposed between the carcass and each turnup extends radially outwardly from the bead core and contacts the carcass along the axially outward surface thereof. A bead cushion element (7) is positioned axially outwardly of each apex strip and turnup combination. Both the apex strip and bead cushion element are formed of a soft rubber compound of high restorability desirably a compound of Shore A hardness of from 50 DEG to 65 DEG and are bound elasticity of 55 to 65% determined according to German industrial Standard DIN 53512.
