A rubber compound having at least two glass transition temperatures Tg1 and Tg2 is based on at least two rubber compositions C1 and C2, C1 comprising at least one elastomer E1 with Tg1, C2 comprising at least one elastomer E2 with Tg2 and a reinforcing filler, E2 being different from E1, where Tg1 is above or equal to -50° C., the rubber compound satisfies Tg1-Tg2 ≥ 23° C. and has a loss factor profile exhibiting the change in tan δ as a function of the temperature in °C. over a range extending from -80° C. to 60° C. at a frequency of 10 Hz and a constant stress of 0.7 MPa and exhibiting one or more peaks, such that all the tan δ peaks present at a temperature above Tg1 have a width at half height less than or equal to 23° C.; and E1 is predominant.
