The present invention relates to a tyre comprising a rubber composition based on at least one reinforcing filler, a polymer comprising conjugated diene functions, and a system for crosslinking said polymer comprising a poly-dienophile of general formula (I) in which - A represents a covalent bond or a hydrocarbon-based group comprising at least 1 carbon atom, optionally substituted and optionally interrupted by one or more heteroatoms, - R 1 , R 2 , R 3 and R 4 represent, independently of one another, identical or different groups selected from the hydrogen atom and hydrocarbon-based groups, R 1 and R 2 on the one hand, and R 3 and R 4 , on the other, being able to form, together with the carbon atoms of the ring to which they are attached, a ring. |
