A tire comprises a rubber composition based on at least one predominant diene elastomer comprising epoxide functional groups, at least one reinforcing filler and a crosslinking system. The crosslinking system comprises a polycarboxylic acid of general formula (I): in which B represents a hydrocarbon group which comprises at least 50 carbon atoms, which is optionally substituted and which is optionally interrupted by one or more heteroatoms, and an imidazole of general formula (II): in which R1 represents a hydrocarbon group or a hydrogen atom, R2 represents a hydrocarbon group, and R3 and R4 represent, independently of one another, a hydrogen atom or a hydrocarbon group, or else R3 and R4 form, together with the carbon atoms of the imidazole ring to which they are attached, a ring. |
