Patent ID: 7060757

Claim:
A high performance pneumatic tire comprising a tread made from a rubber composition comprising (1) a rubber component comprising a styrene-butadiene copolymer rubber having a content of vinyl bond of not less than 30% and a bound styrene content of more than 30 mass % but not more than 60 mass %; (2) at least one compound selected from the group consisting of a compound represented by the following formula (I), a compound represented by the following formula (II), a compound represented by the following formula (III) and a compound represented by the following formula (IV); and (3) an organic thiosulfate compound represented by the following formula (V): wherein R 1 , R 2 , R 3 and R 4 are independently a straight or branched alkyl group having a carbon number of 3–12 or an aralkyl group having a carbon number of 7–12; wherein R 5 and R 6 are independently a straight or branched alkyl group having a carbon number of 7–12 or an aralkyl group having a carbon number of 7–12, and M 1 is a bivalent or polyvalent metal and n is a number equal to an atomic valence of M 1 ; wherein R 7 , R 8 , R 9 and R 10 are independently a straight or branched alkyl group having a carbon number of 3–12 or an aralkyl group having a carbon number of 7–12; wherein R 11 and R 12 are independently a straight or branched alkyl group having a carbon number of 1–18 or a cycloalkyl group having a carbon number of 5–12, and M 2 is zinc, copper or iron and m is a number equal to an atomic valence of M 2 ; M 3 O 3 S—S—(CH 2 ) o —S—SO 3 M 3 (V) wherein o is a number of 3–10 and M 3 is one equivalent weight of lithium, potassium, sodium, magnesium, calcium, barium, zinc, nickel or cobalt, provided that the compound may contain crystal water.
