Abstract
A pneumatic tire produced by processing a rubber composition including a hydrogenated branched conjugated diene copolymer produced by copolymerizing a branched conjugated diene compound and a vinyl compound to form a branched conjugated diene copolymer and hydrogenating the branched conjugated diene copolymer. The branched conjugated diene compound is represented by formula (1), where Ris an aliphatic hydrocarbon having 6 to 11 carbon atoms, the vinyl compound is represented by formula (3), where Ris a hydrogen atom, an aliphatic hydrocarbon group having 1 to 3 carbon atoms, an alicyclic hydrocarbon group having 3 to 8 carbon atoms, or an aromatic hydrocarbon group having 6 to 10 carbon atoms, copolymerization ratio of the branched conjugated diene compound is 1 to 99% by weight, copolymerization ratio of the vinyl compound is 99 to 1% by weight, the branched conjugated diene compound is myrcene and/or farnesene, and the vinyl compound is styrene.
