    摘要： A tire provided with a tire tread made from a rubber composition comprising

    (A) a random copolymer based on non-conjugated cyclic polyene comprising structural units originated from one or more α -olefins (A1) and originated from one or more non-conjugated cyclic polyene (A2), the said random copolymer having a content of the structural unit(s) originated from one or more α -olefins (A1) in the range of 93 to 70 mole %; a content of the structural unit originated from one or more non-conjugated cyclic polyene (A2) in the range of 7 to 30 mole %; an intrinsic viscosity [ η ] , determined in decalin at 135 °C, in the range of 0.01 to 20 dl/g; a glass transition temperature (Tg) of not higher than 40 °C; and an iodine value in the range of 50 to 150, and
    (B) a rubber based on diene,
    in a weight proportion of {the random copolymer based on non-conjugated cyclic polyene (A)} versus {the rubber based on diene (B)} in the range from 60/40 to 0.1/99.9 exhibits a superior braking performance and, compatible therewith, a superior driving fuel cost aspect.
