摘要： A pneumatic tyre comprises a cord-reinforced layer such as carcass (6), belt (7), bead reinforcing layer which is made of metallic cords (10), each metallic cord (10) being made up of six to twelve metallic filaments (F) whose diameter (d) is in a range of from 0.15 to 0.45mm, the metallic filaments (F) including waved filaments (FA) and unwaved filaments (FB), each waved filament (FA) being two-dimensionally waved at a wave pitch (PW) and wave height (h) before twisted, the wave pitch (PW) is in a range of from 5.0 to 35.0 times the diameter (d) of the filament, and the wave height (h) is in a range of from 0.2 to 4.0 times the diameter (d) of the filament, and the metallic filaments (F) are twisted together into the cord (10) at a twist pitch of from 10 to 40mm so that the two-dimensionally waved filaments (FA) are each subjected to a certain rotation around their axis.
