Abstract: A tire comprises 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 said 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 said thermoplastic block.

Abstract: A process for the manufacture of a tyre, one of the parts of the tyre being based on an elastomeric composition comprising an elastomeric matrix and microcapsules, the elastomeric matrix comprising at least 50 phr of a thermoplastic elastomer, and the microcapsules consisting of a polymeric wall coating one or more active products, comprises a stage of addition of the microcapsules to the elastomeric matrix and then of mixing at a mixing temperature Tmixing at which the microcapsules retain their physical and chemical integrity, it being understood that the microcapsules also retain their physical and chemical integrity at the end of the process for the manufacture of the tyre. The boiling or decomposition point of the active product(s) of the microcapsules are greater by at least 30° C. than the glass transition temperature or, if appropriate, greater by at least 30° C. than the melting point of the thermoplastic block(s) of the thermoplastic elastomer in one such tire made by the process.
