Abstract:
The present invention provides a rubber composition for tires which provides a balanced improvement of physical properties including fuel economy, tensile strength, and abrasion resistance while achieving good processability. Also provided is a pneumatic tire formed from the rubber composition. The rubber composition for tires contains: an isoprene-based rubber; and a polybutadiene rubber mixture consisting of a high molecular weight polybutadiene rubber having a cis content of 95% by mass or more and a peak top molecular weight Mp of 550,000 or more and a low molecular weight polybutadiene rubber having a cis content of 95% by mass or more and a peak top molecular weight Mp of 500,000 or less. The rubber component in the rubber composition includes, based on 100% by mass thereof, 60 to 90% by mass of the isoprene-based rubber and 10 to 40% by mass of the polybutadiene rubber mixture.
