The present invention provides a rubber composition for a fiber cord topping which is capable of improving handling stability, fuel economy, elongation at break, adhesion to fiber cords, processability, and tire durability in a balanced manner, and also provides a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition for a fiber cord topping, having an amount of insoluble sulfur with an iron content of not more than 30 ppm, calculated as net sulfur in the insoluble sulfur, of 1.0 to 3.5 parts by mass; a total net sulfur content of 2.0 to 3.5 parts by mass; and a zinc oxide content of 1.5 to 6.0 parts by mass, each per 100 parts by mass of a rubber component of the rubber composition. |
