The present invention aims to provide a rubber composition for a base tread capable of enhancing fuel economy, elongation at break and durability in a balanced manner while maintaining favorable handling stability and processability (extrusion processability) even if the amount of zinc oxide is reduced, and a pneumatic tire having a base tread produced from the rubber composition. The present invention relates to a rubber composition for a base tread including: a rubber component; a compound represented by Formula (I): wherein R1 to R4 each independently represent a C1 to C18 linear or branched alkyl group or a C5 to C12 cycloalkyl group; and zinc oxide, wherein the amount of the compound represented by Formula (I) is 0.2 to 6 parts by mass and the amount of the zinc oxide is 1.0 part by mass or less, relative to 100 parts by mass of the rubber component. |
