Abstract: Elastomeric composition for producing tire components comprising, based upon parts by weight per 100 parts by weight of rubber (phr): (A) 100 phr of a blend of rubber comprising at least 20% by weight of an isoprene polymer; (B) from 0 to 30 phr of silica; (C) from 0 to 50 phr of amorphous carbon black; (D) from 1 to 40 phr of graphene, wherein the graphene consists of graphene nanoplatelets, wherein at least 90% have a lateral size (x, y) from 50 to 50000 nm and a thickness (z) from 0.34 to 50 nm, wherein the lateral size is always greater than the thickness (x, y>z), and wherein the C/O ratio is ≥100:1.
