The invention is to provide a rubber composite and tire using the rubber composite, which, when the rubber composite is used as the tread rubber of a tire, enables the tire to have high wear resistance and hence have a long life while presenting a low rolling resistance and enables an automobile that uses the tires to reduce fuel consumption during traveling. The rubber composite of the invention comprises 100 parts by weight of a rubber component composed of at least one kind of rubber, selected from a group of natural rubber, synthetic isoprene rubber and synthetic diene rubber and 10 to 100 parts by weight of a carbon black blended therein, the carbon black is specified to satisfy the relation X/Y>=0.84, where X is the mercury intrusion specific surface area (m2/g), measured by mercury porosimetry and Y is the CTAB specific surface area (m2/g). The tire of the invention is one that uses the above rubber composite as its tread portion. |
