摘要： The present invention provides a rubber composition and a pneumatic tire using the rubber composition. A rubber composition comprises silica in an amount of 10 to 85 parts by weight per 100 parts by weight of natural rubber and/or diene synthetic rubbers. A polysulfide silane coupling agent having a specific distribution of sulfur reacts with a trivalent phosphorus compound such that a content of high polysulfide in the polysulfide silane coupling agent is reduced. The rubber composition further comprises 1 to 20% by weight, based on an amount of the silica, of the polysulfide silane coupling agent having a specific distribution of sulfur such that a content of high polysulfide component is small. The pneumatic tire has an excellent low heat buildup property.

摘要： A pneumatic tire which comprises a pair of right and left bead portions, a carcass layer disposed extending between the bead portions, a tread portion arranged at an outside of the carcass layer in a radial direction of the tire, a pair of side wall portions arranged at right and left sides of the tread portion and at least one pair of rubber members selected from a pair of rubber members constituted with a rigid rubber and arranged in the bead portions and a pair of rubber members disposed in the side wall portions, wherein at least one pair of rubber members selected from a pair of rubber members arranged in the bead portions and a pair of rubber members disposed in the side wall portions are constituted with rubber composition having a minimum value of a dynamic storage modulus within a temperature range of 200 to 250° C. which is 75% of a dynamic storage modulus at 50° C. or more.
