Abstract

The present invention is directed to a pneumatic tire comprising one or more indicia formed from an elastomeric coating composition comprising a diene based elastomer and from 1 to 100 parts by weight, per 100 parts by weight of elastomer, of a nanoparticle comprising an inner core of an inorganic magnetic material at least partially covered by an outer layer of silica.
