Abstract (en)
[origin: CA3193876A1] The invention concerns a rubber composition based on an elastomer matrix containing 25 to 95 parts per hundred parts by weight of rubber, phr, of a butadiene- and styrene-based copolymer having a glass transition temperature lower than -64° C; 5 to 75 phr of polybutadiene modified with a functional group capable of interacting with silica; at least one reinforcing filler containing silica; at least one coupling agent for coupling the silica to a diene elastomer; 25 to 150 phr of at least one plasticising resin having a glass transition temperature higher than 20° C; and a crosslinking system. The invention also relates to a rubber article and to a pneumatic or non-pneumatic tyre comprising this composition.
