Abstract:
1. A tire comprising an elastomeric composition based on a diene elastomer, an inorganic filler as reinforcing filler and a coupling agent comprising a polysilylated organosilicon compound which is at least bifunctional and is grafted on to the elastomer by means of a sulfur group having a polythiosulfenamide function, of formula: in which: A is a straight-chain or branched divalent bond group, which is capable of joining the polythiosulfenamide group to a first silicon atom of the organosilicon compound; x is an integer or fractional number of from 2 to 4; R R in which: B is a straight-chain or branched divalent bond group; Si represents a second silicon atom of the organosilicon compound.
