Tire component which is not in contact with air or with an inflation gas, comprising a rubber composition based on (a) an elastomeric matrix based on natural rubber, (b) a reinforcing filler, (c) from more than 2.5 to 8.5 phr of sulphur and (d) a dihydrazide compound corresponding to the following formula: in which R is a divalent hydrocarbon radical chosen from substituted or unsubstituted aromatic radicals having 6 to 20 carbon atoms, linear or branched, saturated or unsaturated, aliphatic radicals having 2 to 20 carbon atoms, and n is equal to 0 or 1. These tire components are more particularly those which comprise thread-like reinforcing elements, more especially metallic thread-like reinforcing elements, such as the carcass or crown plies of the tire. |
