ABSTRACT:
Tread rubber compositions or use in automobile tires are disclosed which essentially comprise matrix rubbers and specified amounts of a selected class of low-hardness vulcanized rubbers having specified particle sizes. The matrix and vulcanized rubbers include carbon black, respectively, in amounts defined by the equation 0<X.ltoreq.Y/3 where X is the amount of carbon black present in the vulcanized rubber, and Y is the amount of carbon black in the matrix rubber, each such amount being based on the total weight of the matrix rubber. The resulting tire is rendered highly resistant to snowy and icy conditions and also to abrasive wear.
