Provided in the present invention is a rubber composition for tires which is improved in a dispersibility of silica in a rubber blended with a large amount of silica having so far made it difficult to be kneaded with the rubber and which makes it possible to carry out simultaneously using silica having a large particle diameter and blending a large amount of silica. Used in the present invention is a rubber composition for tires comprising a natural rubber and/or diene base rubber component, a glycerin fatty acid ester composition containing glycerin fatty acid monoester, and silica, wherein a BET specific surface area of the silica is 100 m 2 /g or more and 130 m 2 /g or less, and the rubber composition for tires contains 80 parts by mass or more of the silica based on 100 parts by mass of the rubber component. A tire produced by using the above rubber composition for tires has made it possible to allow a WET performance and a gripping performance to be consistent with an abrasion resistance and has made it possible as well to secure a processability in production by a reduction in a viscosity.
