A tire or tire tread incorporating an elastomeric composition having improved vulcanization kinetics, based on at least a diene elastomer, a reinforcing inorganic filler and, as (inorganic filler/elastomer) coupling agent, a bis-alkoxysilane tetrasulfide of the formula: in which: the symbols R<SUP>1</SUP>, which may be identical or different, each represent a monovalent hydrocarbon group selected from among the group consisting of alkyls, whether straight-chain or branched, having from 1 to 4 carbon atoms, and alkoxyalkyls, whether straight-chain or branched, having from 2 to 8 carbon atoms; R<SUP>2 </SUP>and R<SUP>3</SUP>, which may be identical or different, each represent a monovalent hydrocarbon group selected from among the group consisting of alkyls, whether straight-chain or branched, having from 1 to 6 carbon atoms, and the phenyl radical; and x is between about 3 and about 5. |
