Abstract: A rubber composition includes a rubber component and particulates of a crystalline syndiotactic-1,2-polybutadiene resin dispersed therein. The particulates have an average particle diameter of 1 to 500 .mu.m, and the melting point of the crystalline syndiotactic-1,2-polybutadiene resin is not less than 110.degree. C. The compounding ratio of the resin is 5 to 60 parts by weight relative to 100 parts by weight of the rubber component. The rubber composition is useful for tires, other rubber articles, etc. With respect to tires in particular, a pneumatic tire includes a rubber composition used for a tread, wherein the rubber composition includes a rubber component and particulates of crystalline syndiotactic-1,2-polybutadiene resin. The matrix portion of the tread rubber other than the above particulates is preferably a foamed rubber.

Abstract: A pneumatic tire has a tread with a rubber composition produced by blending a rubber component with a styrene based thermoplastic elastomer. The rubber component is composed mainly of a diene based rubber, and the elastomer is so preliminarily internally crosslinked that tensile stress at a 100% elongation is increased to 10 to 1,000% of that of the styrene based thermoplastic elastomer not internally crosslinked. A pneumatic tire is also disclosed, having a tread portion with a rubber composition blended with a vinyl aromatic hydrocarbon thermoplastic elastomer in an amount of 5-80 parts by weight relative to 100 parts by weight of the rubber component.
