Abstract:
The present invention provides a pneumatic tire having high productivity and achieving a balanced improvement in fuel economy, rubber strength, abrasion resistance, wet-grip performance, and handling stability. The present invention relates to a pneumatic tire including a tread formed from a rubber composition, the rubber composition containing a rubber component in which, based on 100% by mass of the rubber component, the amount of a styrene-butadiene rubber is 15-90% by mass, the amount of a high-cis polybutadiene having a cis content of 95% by mass or more is 5-60% by mass, and the amount of a polyisoprene-based rubber is 0-70% by mass, the rubber composition containing, relative to 100 parts by mass of the rubber component, 10-150 parts by mass of a silica having a nitrogen adsorption specific surface area of 40-400 m2/g, and 1-50 parts by mass of a farnesene resin obtained by polymerizing farnesene.
