Zusammenfassung:	PURPOSE:To provide a tire tread rubber compd. with a good balance between the abrasion resistance and low heat build-up by adjusting the aggregate anisotropy dependent on the void volume of aggregates and controlling the width of aggregate distribution within a specified range. CONSTITUTION:The title carbon black comprises a carbon black which belongs to the hard grade such as one having a nitrogen adsorption specific surface area (N2SA) of 60-160m and a DBP adsorption (DBP) of 90-150ml/100g and in which the void volume of aggregates, Vp(ml/g), satisfies Vp>=0.00976XDBP-0.0358 and the aggregate properties (centrifugal precipitation method) satisfies Dst/(0.601XDst+4.02)
