A tread for a tire, the tread comprising a rubber composition that is based upon a cross-linkable elastomer composition, the cross-linkable elastomer composition comprising, per hundred parts by weight of rubber (phr), a high-Tg rubber being a highly unsaturated diene elastomer having a glass transition temperature of between −30° C. and 0° C., a low-Tg rubber being a highly unsaturated diene elastomer having a glass transition temperature of between −110° C. and −60° C. The high-Tg and the low-Tg elastomers are incompatible and this provides, among other advantages, improved snow traction of the tread when compared to tire treads having lower Tg.
