Furthermore, these polyaldehyde compounds make it possible not only to obtain rubber compositions exhibiting the same low-strain stiffness as conventional rubber compositions using HMT or H3M
methylene donors, but also, surprisingly, to greatly improve the fatigue strength of the rubber compositions and thus the endurance of the tires.

The pair formed of epoxide resin with an amine-comprising curing agent advantageously replaces the pair formed of phenolformaldehyde resin, which is a methylene acceptor, with the curing agent(s) HMT or H3M
, which are conventional methylene donors.
