A tire comprising a polymeric composition comprising at least one block thermoplastic elastomer comprising at least one elastomer block and at least one thermoplastic block, in which each elastomer block comprises at least 70% by weight of units resulting from isoprene, with respect to the weight of the at least one elastomer block, and at least one thermoplastic block comprises 40% to 80% by weight of units resulting from one or more styrenic monomers and 10% to 63% by weight of units resulting from diphenylethylene, with respect to the weight of the at least one thermoplastic block.
