The present invention relates to the use in a silica-filled rubber composition of an aminosilane compound of the formula (see formula) wherein R1, R2 and R3 are independently selected from the group consisting of alkoxy radicals having from 1 to 8 carbon atoms, alkyl radicals having 1 to 8 carbon atoms and aryl radicals having t carbon atoms, with the proviso that at least one of R1, R2 and R3 is an alkoxy radical; R4 is selected from the group consisting of alkylene groups having from 1 to 18 carbon atoms and arylene and alkyl substituted arylene groups having from 6 to 10 carbon atoms; R5 is selected from the group consisting of hydrogen and alkyl groups having from 1 to 15 carbon atoms. La presente invencion se relaciona con el uso de una composicion de caucho cargada de sílice, de un compuesto de aminosilano de la formula (I): en donde R1, R2 y R3 se seleccionan independientemente del grupo que consiste de radicales de alcoxi que tienen de 1 a 8 átomos de carbono, radicales de alquilo que tienen de 1 a 8 átomos de carbono y radicales de arilo que tienen 6 átomos de carbono con la salvedad de que por lo menos uno de R1, R2 y R3 es un radical de alcoxi; R4 se selecciona del grupo que consiste de grupos de alquileno que tienen de 1 a 18 átomos de carbono y grupos de arileno que tienen de 1 a 18 átomos de carbono y grupos de arileno y de arileno alquil-substituido que tienen de 6 a 10 átomos de carbono; R5 se selecciona del grupo que consiste de hidrogeno y grupos de alquilo, que tienen de 1 a 15 átomos de carbono.
