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 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 .
