The invention relates to an item made of rubber, selected from among tires for civil engineering vehicles, caterpillar tracks and conveyor belts, that exhibits a good performance trade-off between resistance to mechanical attack and hysteresis. This rubber item comprises a composition based on at least: an elastomeric matrix comprising at least 55% by weight of at least one isoprenic elastomer having a molar cis-1,4 bond content of at least 90%; a thermoplastic elastomer comprising at least one polyether elastomer block and at least one non-styrenic thermoplastic block, the thermoplastic elastomer having a melting point, Tf, within a range from 130°C to 175°C; 10 to 60 PHR carbon black; 5 to 30 PHR silica; and a crosslinking system; the carbon black representing from 55% to 95% by weight relative to the total weight of carbon black and silica.
