Abstract

A rubber composition for a tire contains 100 parts by mass of a diene rubber (A) and from 1 to 60 parts by mass of an organic microparticle (B); an average particle size of the organic microparticle (B) being from 0.001 to 100 μm, the organic microparticle (B) having a complex structure composed of a compatible component that is compatible with the diene rubber (A) and an incompatible component that is not compatible with the diene rubber (A), the complex structure having an inner part in which an amount of the incompatible component is greater than an amount of compatible component, and an outer part which covers at least a part of the inner part and in which the amount of the compatible component is greater than an amount of the incompatible component. A pneumatic tire including such rubber composition has a desirable elongation, rigidity, durability, and wear resistance.
