Provided are rubber compositions for tires capable of providing tire components and pneumatic tires that have the same level of fuel efficiency and wet grip performance (particularly, wet grip performance) as those of tire components and pneumatic tires containing conventional synthetic rubber, while satisfying the requirements for a sound material-cycle society. The present invention relates to rubber compositions for tires containing a biomass-derived rubber polymerized from an aromatic vinyl compound and a diene, the biomass-derived rubber having a pMC (percent modern carbon) measured in accordance with ASTM D 6866-10 of 1% or higher.
