  "textContent": "The present invention provides a rubber composition for a tire which can achieve both high levels of fuel economy and abrasion resistance, as well as excellent wet grip performance; and a pneumatic tire produced using the rubber composition. The rubber composition for a tire includes a rubber component that includes 5% by mass or more of a modified styrene butadiene rubber containing a constitutional unit derived from a specific nitrogen-containing compound in a main chain, based on 100% by mass of the rubber component; silica; and a compound represented by the following formula (I): R 20 -S-S-A-S-S-R 21 (I) wherein A represents a C2 to C10 alkylene group, and R 20 and R 21 are the same as or different from each other, each representing a monovalent organic group that contains a nitrogen atom.",
