The present invention relates to a tyre comprising a rubber composition based on at least one predominant diene elastomer comprising epoxide functions, at least one reinforcing filler, and a crosslinking system comprising a polycarboxylic acid of general formula (I) in which B is a hydrocarbon-based group comprising at least 50 carbon atoms, which is optionally substituted and optionally interrupted with one or more heteroatoms, and an imidazole of general formula (II) in which - R1 is a hydrocarbon-based group or a hydrogen atom, - R2 is a hydrocarbon-based group, - R3 and R4 are, independently of one another, a hydrogen atom or a hydrocarbon-based group, or else R3 and R4 form, together with the carbon atoms of the imidazole ring to which they are attached, a ring (img file='DDA0000739892220000011.
