摘要

A tire composition comprising at least one rubber composition based on at least one diene elastomer, and a process for preparing a rubber composition based on at least one diene elastomer. The invention relates to a tire comprising at least one rubber composition based on at least one diene elastomer, a reinforcing filler, a chemical crosslinking agent and a modifying agent selected from the compounds of formula I below: wherein: R2 represents a moiety containing at least one reactive group, R2 represents hydrogen, R2 represents an alkylene radical comprising from 2 to 8 carbon atoms and optionally one or more heteroatoms chosen from s, si, and a. represents an oxygen or sulfur atom or a group -nh, and preferably an oxygen atom.
