A rubber composition is disclosed comprising, based on 100 parts by weight of elastomer (phr): at least three diene elastomers each being a different rubber material, the elastomers comprising: (a) polybutadienes comprising: (i) a majority portion of a first polybutadiene synthesized with a lanthanide series catalyst, the first polybutadiene having a first Mooney viscosity; (ii) a minority portion of a second polybutadiene synthesized with a Nickel-based catalyst, the second polybutadiene having a Mooney viscosity within ± 5 MU of the Mooney viscosity of the first polybutadiene; (b) a synthetic polyisoprene; wherein each of the at least three elastomers has a cis content of greater than 80 percent or greater than 90 percent.
