Rubber composition for tire tread and tire |
| abstract |
Provided is a rubber composition for a tire tread, the composition containing: a rubber constituent that includes at least 70% by mass of natural rubber; at least one chosen from the group consisting of zinc oxide, fatty acids, and fatty acid zinc, at a total content of at least 2 parts by mass and less than 13 parts by mass relative to 100 parts by mass of the rubber constituent; a filler that includes carbon black; and a carbon black dispersant. A vulcanized rubber formed of the rubber composition for a tire tread is such that the integrated white-area value with a grain diameter of at least 32 µm is 15% or less of the integrated white-area value with a grain diameter of 3–57 µm when a cross-section is measured using a dispersion grader that is in compliance with ASTM D7723. |
