The present invention relates to a tire for vehicle wheels which comprises at least one structural component comprising at least one reinforcing element constituted by an elongate element coated with, or embedded in, a vulcanised elastomeric compound obtained by vulcanising an 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 and a quantity of lignin equal to or greater than 20 phr, (ii) from 0 to 90 phr of a diene elastomeric polymer, (iii) at least 30 phr of a carbon black reinforcing filler, (iv) optionally, a reinforcing resin comprising at least 0.5 phr of a methylene acceptor compound associated with at least 0.2 phr of a methylene donor compound, (v) from 0.1 to 10 phr of carbon nanotubes, and (vi) from 0.1 to 12 phr of at least one vulcanising agent, wherein at least 50 phr of said diene elastomeric polymer is constituted by natural or synthetic isoprene rubber.
