    Abstract: A steel cord (10) has a diameter D and comprises a core strand (12) and up to nine peripheral strands (14) surrounding the core strand. The core strand (12) has a diameter D1 and the peripheral strands (14) have a diameter D2. The ratio core strand diameter to peripheral strand diameter D1/D2 is greater than a predetermined value in order to enable rubber penetration. Each strand comprises a centre of one or more centre filaments (16,22) and two or more layers of filaments (18,20,24,26) surrounding the centre.
    The twist angle of a radially outer layer is smaller than the twist angle of a radially inner layer of the same strand. A first free space (28) ranging from 0.0015xD to 0.0075xD is provided in at least the core strand (12) between each pair of filaments (18) of the radially most inner layer.
