NOVELTY - An elastomeric composition comprises 100 parts per hundred rubber (phr) of blend of rubbers (A) comprising greater than or equal to 20 wt.% isoprene polymer, 0-30 phr of silica (B), 0-50 phr of amorphous carbon black (C), and 1-40 phr of graphene (D) based on 100 parts per hundred rubber (phr). Graphene comprises nanoplatelets of graphene, in which greater than or equal to 90% of nanoplatelets have lateral size (x, y) of 50-50000 nm and thickness (z) of 0.34-50 nm, and lateral size is always greater than the thickness (x, y= greater than or equal to z), and carbon/oxygen (C/O) ratio is greater than or equal to 100:1. USE - An elastomeric composition for tire component e.g. tread, inner tube, tubeless tire and inner liner of tubeless tire, or carcass of bicycle tire (all claimed). ADVANTAGE - The elastomeric composition allows improvement in balance of properties between rolling resistance and wet grip of tire, e.g. allows good compromise to be reached between values of the parameters without having particular negative impact on either. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for tire component comprising elastomeric composition.
