A rubber composition is disclosed. The composition comprises a blend based on 100 parts by weight (phr) of diene elastomers: 5 to 95 phr of a first diene elastomer, 5 to 50 phr of a hydrogenated styrenic block copolymer (HSBC), 50 to 200 phr of a filler, up to 25 phr of a plasticizer. The HSBC has a melt flow ratio of 1.0 to 50.0 measured according to ASTM D-1238 at 230° C. and 2.16 kg load, a Shore A hardness of 40 to 80 measured according to ASTM D-2240, a DMA peak tan delta temperature of 0° C. to 40° C. at 1 Hz measured according to ASTM D-4065, and an order-disorder transition temperature of 200° C. to 300° C. The composition does not comprise a resin, a plasticizer, or comprises a resin or a plasticizer in an amount of less than 20 phr.
