A method of forming a sulfur-vulcanized elastomeric by combining at least one diene elastomer and at least one reinforcing filler, with an effective amount of a coupling agent consisting of a combination of: 10 to 90%, of a product (I) consisting of a blend of poly(alkylphenol) polysulfides of formula: in which: R is an alkyl radical containing 1 to 20 carbon atoms; n and n' are two integers, which may be identical or different, from 1 to 8; p is an integer from 0 to 50; and 10 to 90% of a product (II) consisting of bis(triethoxysilylpropyl)tetrasulfide, to form a mixture; thereafter working said mixture; and thereafter heating said mixture to vulcanize said mixture. 90% of bis(triethoxysilylpropyl)tetrasulfide.
