Abstract:
    The invention concerns a crosslinkable or crosslinked rubber composition having improved hysteretic properties when crosslinked which is useful for forming a tyre running tread, a method for preparing said crosslinkable composition, such a running tread and a tyre having reduced rolling resistance. Said composition is characterised in that it consists of: at least a diene elastomer having a mol ratio of units derived from conjugate dienes higher than 30 % and comprising carboxylic acid functions along its chain, and a reinforcing inorganic filler.
