Abstract:
A tire comprises a tread, a crown with a crown reinforcement, two sidewalls, two beads, a carcass reinforcement anchored to the two beads and extending from one sidewall to the other, characterized in that the tread comprises a composition based on at least a diene elastomer, at a content of between 35 and 99 phr (parts by weight per hundred parts of elastomer), a thermoplastic elastomer system, at a total content of between 1 and 65 phr, said thermoplastic elastomer system comprising at least two block copolymers, referred to as polystyrene and poly(butadiene/styrene) block copolymers, each comprising at least one elastomer block of optionally hydrogenated butadiene/styrene random copolymer type, and at least one thermoplastic block of styrene type, one of the two polystyrene and poly(butadiene/styrene) block copolymers being hydrogenated such that a proportion ranging from 95 to 100 mol % of the double bonds in the butadiene portion is hydrogenated, the latter being referred to as an essentially hydrogenated polystyrene and poly(butadiene/styrene) block copolymer.
