  • Tire tread compositions having improved low temperature properties
    Patent number: 4012344
    Abstract: Tires having both improved wet skid resistance and low temperature performance properties are prepared by blending into conventional tire tread compositions a copolymer of isobutylene and cyclopentadiene (CPD) having a CPD content of between 5 and less than 20 mol %. The tire tread composition preferably contains about 30 wt. % of cyclopentadiene copolymer. Low temperature properties are improved compared to compositions containing greater than 20 mol % CPD in the copolymer.
