Abstract
Provided are a rubber composition for tires that shows a balanced improvement in properties such as fuel economy, processability, heat aging resistance, abrasion resistance, wet-grip performance, performance on snow and ice, and handling stability, and a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition for tires, containing: a highly purified, modified natural rubber having a pH adjusted to 2 to 7, and a silica having a CTAB specific surface area of 180 m2/g or more and a BET specific surface area of 185 m2/g or more, and also relates to a pneumatic tire formed from the rubber composition.
