    摘要: 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 CO2 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/cm3 or more.

    摘要: The present invention provides a rubber composition for a tread, which is friendly to the global environment and can prepare for the decrease in oil supply in the future because of its high content of non-fossil resources, as well as shows an excellent running performance (braking performance) on a wet road surface and a dry road surface, and has an improved abrasion resistance. The present invention also provides a pneumatic tire in which the rubber composition for a tread is used for a tread of the tire. The rubber composition for a tread of the present invention includes a rubber component containing butadiene rubber and 35% by mass or more of epoxidized natural rubber, and a white filler.
