Abstract (en)
[origin: WO2015181150A1] The present invention relates to a radial tyre (1) for a motor vehicle, comprising a crown (2) having a tread (3) provided with at least one radially external portion (3a) intended to enter into contact with the road; two inextensible beads (4), two sidewalls (5) linking the beads (4) to the tread (3), a carcass reinforcement (6) passing into the two sidewalls (5) and anchored in the beads (4); a crown reinforcement or belt (7) disposed circumferentially between the radially external portion (3a) of the tread (3) and the carcass reinforcement (6); a radially internal elastomer layer (8), called "sub-layer", different in composition from the composition of the radially external portion (3a) of the tread, said sub-layer itself being disposed circumferentially between the radially external portion (3a) of the tread (3) and the carcass reinforcement (6), characterized in that said sub-layer comprises at least one thermoplastic elastomer, said thermoplastic elastomer being a block copolymer comprising at least one elastomer block and at least one thermoplastic block, the total amount of thermoplastic elastomer being in a range varying from 65 to 100 phr (parts by weight per hundred parts of elastomer), said sub-layer also comprising at least one conductive filler.
