The invention aims to provide a rubber composition for outer layers of tires capable of reducing the generation of odors while maintaining or improving good elongation at break and processability, and a pneumatic tire using the same. Included is a rubber composition for outer layers of tires, including: a rubber component; a nonionic surfactant or polyethylene glycol; and a vulcanization accelerator represented by formula (1) below, the rubber component including a diene rubber in an amount of 70-100% by mass based on 100% by mass of the rubber component, the rubber composition including, per 100 parts by mass of the rubber component, 0.2-6.0 parts by mass of the nonionic surfactant or polyethylene glycol, 0.2-10 parts by mass of the vulcanization accelerator, and not more than 0.5 parts by mass of N-tert-butyl-2-benzothiazolylsulfenamide, wherein R 11 represents a C2-C16 alkyl group, and R 12 represents a C3-C16 branched alkyl group or a benzothiazolylsulfide group.
