Zusammenfassung: | A tire having a tread composed of a rubber composition comprising: a rubber component comprising a butadiene rubber and a styrene-butadiene rubber and carbon black, wherein an X part by mass of a content of the carbon black based on 100 parts by mass of the rubber component and a Y nm of an average particle size of the carbon black satisfy the following equation (1), the styrene-butadiene rubber and the butadiene rubber form a bicontinuous structure, a distribution ratio α of the carbon black in the styrene-butadiene rubber is 1.5 or more and 1.9 or less, and a distribution ratio β of the carbon black in the butadiene rubber is 0 or more and 0.6 or less.0.11≤X/Y2≤0.26 |
