摘要

PROBLEM TO BE SOLVED: To provide a rubber composition for a tire, which can obtain a crosslinked rubber composition having a high dynamic storage elastic modulus without deteriorating processability. Another object is to provide a rubber additive to be added to the rubber composition and the rubber additive composition. Furthermore, it is to provide a rubber product for a tire and a tire using the rubber composition or the crosslinked rubber composition. A rubber composition for a tire, comprising a rubber component, a vulcanizing agent, and a compound represented by the following formula (I). (In formula (I), R
