  "textContent": "Provided are a vulcanized rubber composition and a pneumatic tire in which the combined performance of low fuel consumption performance and wet grip performance is enhanced. In the vulcanized rubber composition, the amount of styrene-butadiene rubber contained in 100% by mass of a rubber component is 10 to 100% by mass, 5 to 200 parts by mass of a resin is contained per 100 parts by mass of the rubber component, and, when transmission measurement by Fourier-transform infrared spectroscopy is performed both before and after acetone extraction, a peak around 1600 cm-1 is shifted by not less than 0.9 cm-1 between before and after the acetone extraction.",
