  "textContent": "A rubber compound for the preparation of a tread portion of a pneumatic tyre. The compound comprises at least one cross-linkable unsaturated chain polymer base capable of assuming all of the chemical-physical and mechanical characteristics of an elastomer after cross-linking, a filler comprising silica, a plasticizing agent and a curing system. The cross-linkable unsaturated chain polymer base has a peak Tan δ value between −15° C. and 5° C. while the plasticizing agent is made up of an aliphatic chain comprising at least one polar group and has a melting temperature of between 5° C. and 40° C.",
