ABSTRACT DIENE ELASTOMER COMPOSITIONS Disclosed is a diene elastomer composition especially suitable as tread rubber of tires which has low rolling resistance and high wet grip in combination. This elastomer composition contains a rubber material comprising an elastomeric polymer component of a butadiene polymer and/or a styrene-butadiene copolymer and a rubbery component. The elastomeric polymer is produced by using an organolithium compound as a polymerization initiator, and has a long chain end concentration (LCEC) of 1.5 or less as defined by the following formula: LCEC = ?.beta.i x (.alpha. x 105) / (MW)i wherein .alpha.: total number of terminal groups in long chain molecules per polymer, MW: a value obtained from intrinsic viscosity of the polymer as measured in toluene at 30°C by the following formulas: MW = 70 660 x [n]1.232 for styrene-butadiene copolymer, MW = 79,167 x [n]1.443 for butadiene polymer, .beta.i: weight fraction of component i when MW = (MW)i.
