A tyre for vehicle wheels comprising:
- a carcass structure, having opposite lateral edges associated with respective bead structures;
- optionally, a belt structure applied in a radially external position with respect to the carcass structure;
- a tread band applied in a radially external position with respect to the carcass and/or belt structure;
- wherein the tread band comprises a cross-linked elastomeric material copmprising, before cross-linking, a cross-linkable elastomeric composition, wherein the elastomeric composition comprises at least one iso-styrene/trans-butadiene/terpene random terpolymer, the iso-styrene/trans-butadiene/terpene random terpolymer having a styrene content ranging from 30% to 70% by weight with respect to the total weight of terpolymer, a terpene content ranging from 1% to 15% by weight with respect to the total weight of terpolymer, and a content of 1,4-butadiene ranging from 30% to 70% by weight with respect to the total weight of terpolymer.
