    摘要： A radial tire having an under-tread layer between a cap tread and a breaker layer is disclosed. As the material for the cap tread, a rubber composition is employed which contains 0.5 to 1.6 parts by weight of sulfur per 100 parts by weight of starting rubber components consisting of 25 to 75 parts by weight of polybutadidne rubber having 65 to 90 mol % of 1,2-bonding units and 75 to 25 parts by weight of natural rubber and/or polyisoprene rubber, and which has elongation at break of at least 330% at 100.degree. C. A rubber composition containing 1.6 to 10 parts by weight of sulfur per 100 parts by weight of rubber components is used for the under-tread layer.

    摘要： A process for preparing a tire tread rubber composition having improved rolling resistance and wet skid resistance comprising [I] 100 parts by weight of a rubber material composed of 25 to 75% by weight of substantially amorphous polybutadiene having a 1,2-bond unit content of 65 to 90 mole % and a Mooney viscosity (ML.sub.1+4, 100.degree. C.) of 20 to 100 and 75 to 25% by weight of natural rubber and/or cis-1,4-polyisoprene, and [II] 40 to 70 parts by weight of carbon black, said process comprising (1) mechanically compounding 40 to 60 parts by weight of the rubber material [I] with 40 to 70 parts by weight of carbon black [II], and then (2) adding to the resulting mixture the rubber material [I] in an amount sufficient to adjust the amount of the carbon black [II] to 40 to 70 parts by weight per 100 parts by weight of the rubber material [I] and mechanically compounding them.
