The present invention has its object to provide a rubber composition for a tread which can prevent reversion and can also achieve environmental performance (excellent rolling resistance, response to depletion of oil resources, attention to CO 2 emission), wet grip performance, dry grip performance, handling stability, and durability (abrasion resistance, crack resistance) in a well-balanced manner. The present invention also aims to provide a pneumatic tire using the rubber composition for the tread thereof. The rubber composition for a tread includes a rubber component containing 35% by mass or more of an epoxidized natural rubber; and a white filler, wherein a total sulfur content is less than 1.75% by mass, and a crosslink density is 7.0 × 10 -5 mol/cm 3 or more. |
