| titleOfInvention | Pneumatic tires |
| abstract | Abstract of the Disclosure A pneumatic tire having a tread is disclosed, which comprises using in said tread a rubber composition containing 10 to 120 parts by weight of carbon black and 0.5 to 5 parts by weight of a vulcanizer based on 100 parts by weight of a novel styrene-butadiene copolymer rubber as defined below alone or a blend rubber of not less than 30 parts by weight of said copolymer rubber and not more than 70 parts by weight of the other diene rubber, said styrene-butadiene copolymer rubber being obtained by random copolymerization of styrene with 1,3-butadiene and satisfying the following requirements: (1) a content of bound styrene is 10 to 30% by weight; (2) a content of 1,2-bond in butadiene portion is 42 to 70% by weight; (3) a content of trans-1,4 bond in butadiene portion is not less than 25% by weight; (4) a value obtained by subtracting a content of cis-1,4 bond in butadiene portion from said content of trans-1,4 bond is not less than .8% by weight; (5) a relation between said content of bound styrene and said content of 1,2-bond is 65 < 1.7 x the content of bound styrene (% by weight) + the content of 1,2-bond (% by weight) < 100; (6) a weight mean molecular weight (?w) is 35 x 104 to 65 x 104; (7) a ratio of weight mean molecular weight (?w) to number mean molecular weight (?n) is not more than 2.3; (8) the number of peaks in molecular weight distribu-tion curve is not less than 2; and (9) a relation between said weight mean molecular weight and said content of trans-1,4 bond is 75 < ?w x 10-4 + 1.3 x the content of trans-1,4 bond (% by weight) < 120. |
