A rubber composition based at least on an elastomer matrix, on a reinforcing filler and on a vulcanization system is provided. The elastomer matrix comprises a highly saturated elastomer and from 0 to less than 30 phr of natural rubber. The highly saturated diene elastomer contains 1,3-diene units and more than 50 mol % of ethylene units. The vulcanization system comprises a dithiosulfate salt of formula MO3S—S-A-S—SO3M in which the symbol A represents an alkanediyl group or a group comprising two or more alkanediyl units, which units are connected in pairs via an oxygen or sulfur atom, via a group of formula —SO2—, —NH—, —NH2+—, —N(C1-C16 alkyl)- or —COO—, or via an arylene or cycloalkylene group, and the symbol M represents a metal atom. The invention makes it possible to achieve an improved compromise between bubble formation in the rubber composition on exiting from the curing presses and its hysteresis.
