Abstract (en)
[origin: WO2011147712A1] The invention relates to a radial tire (1) for a motor vehicle, comprising: a crown (2) comprising a tread (3) provided with at least one radially outer portion (3a) intended to come into contact with the road; two inextensible beads (4), two sidewalls (5) joining the beads (4) to the tread (3), a carcass reinforcement (6) running into the two sidewalls (5) and anchored in the beads (4); a crown reinforcement or belt (7) arranged circumferentially between the radially outer portion (3a) of the tread (3) and the carcass reinforcement (6); a radially inner elastomeric layer (8) referred to as an "inner crown layer", of a different composition from the composition of the radially outer portion (3a) of the tread, said inner crown layer being arranged circumferentially either between the radially outer portion (3a) of the tread (3) and the crown reinforcement (7), or between the crown reinforcement (7) and the carcass reinforcement (6), characterized in that said inner crown layer (8), which is capable of reducing the rolling noise of the tire, comprises a rubber composition containing 50 to 100 percent of a styrene and butadiene-based colpolymer having a Tg greater than -40°C, a reinforcing filler, a hydrocarbonated plasticizing resin and a cross-linking system.
