The present invention relates to a tyre for vehicle wheels which comprises at least one structural element comprising a vulcanised elastomeric compound obtained by vulcanisation of a vulcanisable elastomeric composition comprising per 100 phr of diene elastomeric polymer: (i) a predispersion of a diene elastomeric polymer and nanometric lignin, in an amount to provide the elastomeric composition with 100 to 10 phr of diene elastomeric polymer and an amount of nanometric lignin equal to or greater than 5 phr, (ii) from 0 to 90 phr of at least one diene elastomeric polymer, (iii) from 0 to 110 phr of a reinforcing filler, (iv) from 0.1 to 12 phr of at least one vulcanising agent, where said nanometric lignin comprises lignin particles having an average hydrodynamic diameter D50 lower than 500 nm and greater than 50 nm.

Abstract
The present invention relates to a tyre for vehicle wheels which comprises at least one structural element comprising a vulcanised elastomeric compound obtained by vulcanisation of a vulcanisable elastomeric composition comprising per 100 phr of diene elastomeric polymer: (i) a predispersion of a diene elastomeric polymer and nanometric lignin, in an amount to provide the elastomeric composition with 100 to 10 phr of diene elastomeric polymer and an amount of nanometric lignin equal to or greater than 5 phr, (ii) from 0 to 90 phr of at least one diene elastomeric polymer, (iii) from 0 to 110 phr of a reinforcing filler, (iv) from 0.1 to 12 phr of at least one vulcanising agent, where said nanometric lignin comprises lignin particles having an average hydrodynamic diameter D50 lower than 500 nm and greater than 50 nm.
