<p>A reduced heat-buildup rubber composition prepared by compounding 100 parts by weight of either a polymer prepared by the reaction of a conjugated diene polymer terminated with an alkali metal atom and a specified tin compound or a rubber blend comprising at least 30 parts by weight of said polymer and other diene polymer with 20 to 100 parts by weight of a reinforcing filler, 0.1 to 5 parts by weight of 2,5-dimercapto-1,3,4-thiadiazole, and 0.2 to 10 parts by weight of a specified nitrogen or sulfur compound. The composition is useful over a wide application range and particularly suitable for a tire of low fuel consumption.</p> |
