Tyres for vehicle wheels

The present invention relates to a tyre for vehicle wheels which comprises at least one structural element comprising a vulcanized elastomeric compound obtained by vulcanization of a vulcanizable elastomeric composition comprising per 100 phr of diene elastomeric polymer: (i) a predispersion of a diene elastomeric polymer and lignin, in an amount to provide the elastomeric composition with 100 to 10 phr of diene elastomeric polymer an amount of lignin equal to or greater than 5 phr, (ii) 0 to 90 phr of at least one diene elastomeric polymer, (iii) 5 to 50 phr of a reinforcing filler, (iv) from 0.1 to 12 phr of at least one vulcanizing agent, wherein said lignin is lignin functionalised with an acyl group represented by the following formulas (1) and (2): where R1, R2, R3 and R4 are as defined in the description.
