Abstract
The present invention provides a rubber composition, containing 10 parts by mass or more and 90 parts by mass or less of a rubber-like polymer having an iodine value of 10 to 200 (g/100 g), a content of an ethylene structure of 3% by mass or more, a content of an aromatic vinyl monomer block of less than 10% by mass, and a content of a conjugated diene monomer unit of 2% by mass or more; 10 parts by mass or more and 90 parts by mass or less of a natural rubber; and 20 parts by mass or more and 80 parts by mass or less of a silica-based inorganic filler and a carbon black, with respect to 100 parts by mass of a total amount of a rubber component.

A rubber composition, comprising:
- 10 parts by mass or more and 90 parts by mass or less of a rubber polymer having an iodine value of 10 to 200 (g/100 g), a content of an ethylene structure of 3% by mass or more, a content of an aromatic vinyl monomer block of less than 10% by mass, and a content of a conjugated diene monomer unit of 2% by mass or more;
- 10 parts by mass or more and 90 parts by mass or less of a natural rubber;
- and
- 20 parts by mass or more and 80 parts by mass or less of a silica-based inorganic filler and a carbon black, with respect to 100 parts by mass of a total amount of a rubber component comprising the rubber polymer and the natural rubber,
- wherein a content of the silica-based inorganic filler is 60 parts by mass or less, and a content of the carbon black is 60 parts by mass or less.
