Patent ID: 6903155

Claim:
A heavy-vehicle tire comprising a tread which is formed from a cross-linked rubber composition, the composition comprising: (a) an elastomeric matrix comprising a functionalized diene elastomer co-polymer formed from a conjugated diene monomer and a vinyl-aromatic compound, the co-polymer having a glass transition temperature between −70° C. and −20° C. and a mass content of vinyl-aromatic units of from 10% to 50%, the elastomer having at one or more of its chain ends a functional group which is active for coupling to a reinforcing white filler, the functional group being selected from the group consisting of a silanol group and a polysiloxane block having a silanol end; (b) a reinforcing filler comprising at least 50% by weight of silica, the silica having a CTAB specific surface area of from 80 m 2 /g to 260 m 2 /g; and (c) a reinforcing white filler/functionalized diene elastomer bonding agent.
