Abstract: In tire tread formulations, blends of rubbers having low and high glass transition temperatures have significant advantages over blends made with rubbers having intermediate glass transition temperatures. However, blends of rubbers having low and high glass transition temperatures exhibit poor processability. This invention deals with improving the processability of tire tread formulations which are made by blending rubbers having both low and high glass transition temperatures that offer ultra low rolling resistance without sacrificing rolling resistance or tread wear characteristics. This invention more specifically discloses a tire tread rubber composition which is comprised of (a) about 60 phr to about 90 phr of a high cis-1,4-polybutadiene rubber, wherein the high cis-1,4-polybutadiene rubber has a glass transition temperature which is within the range of about −104° C. to about −80° C., (b) about 10 phr to about 40 phr of at least one additional rubbery polymer selected from the group consisting of polyisoprene rubber, polybutadiene rubber and styrene-isoprene-butadiene rubber, wherein the additional rubbery polymer has a glass transition temperature which is within the range of about −30° C. to about −10° C. isoprene-butadiene rubber, (c) about 20 phr to about 60 phr of carbon black, wherein the carbon black has a DBP absorption value of at least 140 cm3/100 grams and wherein the carbon black has a CTAB adsorption area which is within the range of about 60 to about 90.

Abstract: This invention relates to a tire tread compound that is easily processable which can be used to improve the treadwear, rolling resistance and traction characteristics of tires. The tire tread compounds of this invention are a blend of tin-coupled polybutadiene, high vinyl polybutadiene and natural rubber. This blend of low glass transition temperature rubber and high glass transition temperature rubber is surprisingly easy to process which makes the concept of this invention commercially feasible. Thus, the tire tread compounds of this invention can be utilized in making tires having greatly improved traction characteristics and treadwear without sacrificing rolling resistance. These improved properties may be due, in part, to better interaction and compatibility with carbon black and/or silica fillers. The polybutadiene in the blend can be asymmetrical tin-coupled to further improve the cold flow characteristics of the rubber blend. Asymmetrical tin coupling in general also leads to better processability and other beneficial properties. This invention more specifically discloses a tire tread rubber composition which is comprised of (1) from about 20 phr to about 60 phr of tin-coupled polybutadiene rubber, (2) from about 20 phr to about 60 phr of a rubber selected from the group consisting of natural rubber and synthetic polyisoprene and (3) from about 5 phr to about 40 phr of high vinyl polybutadiene rubber.
