The rubber composition for treads, and a pneumatic tire
Document Type and Number:
Japanese Patent JP6018207
Kind Code:
B2
Abstract:
Provided are: a rubber composition for a tread, which has excellent abrasion resistance and good wet grip performance and can have good fuel efficiency and good elongation at break; and a pneumatic tire (particularly a tire for a passenger car or a tire for a versatile sports car) which is produced using the rubber composition. The present invention relates to a rubber composition for a tread, in which the content of a modified butadiene rubber for silica which has a cis content of 50 mass% or less is 8 to 40 mass% and the content of a styrene-butadiene rubber is 25 to 75 mass% both relative to 100 mass% of rubber components, and silica having a nitrogen adsorption specific surface area of 160 to 270 m2/g is contained in an amount of 40 to 120 parts by mass relative to 100 parts by mass of the rubber components.
