An airtight elastomeric laminate for tires comprises at least two superimposed layers of elastomer. The first layer is composed of a composition based on at least one thermoplastic elastomer having polystyrene and polyisobutylene blocks, the content of thermoplastic elastomer having polystyrene and polyisobutylene blocks being within a range extending from more than 50 to 100 phr and on a plasticizing system comprising from 1 to 40 phr of a plasticizing oil and from 1 to 40 phr of a hydrocarbon resin, the total content of plasticizer being within a range extending from 2 to 70 phr. The second layer is composed of a composition based on at least one diene elastomer, the content of diene elastomer being within a range extending from more than 50 to 95 phr, and on at least one thermoplastic styrene elastomer in an amount ranging from 5 to less than 50 phr.
