Abstract

Provided are a rubber composition for a tire, in which while the use of petroleum resources is reduced as much as possible, the compatibility of microfibrillated plant fibers with the rubber component is enhanced by a simple method, which can lead to a balanced improvement in tensile properties, handling stability, and fuel economy; a method of producing the rubber composition; and a pneumatic tire formed from the rubber composition. The rubber composition for a tire contains a rubber component; microfibrillated plant fibers; and natural shellac resin. It is preferable that the rubber component should include at least one selected from the group consisting of natural rubber, modified natural rubber, synthetic rubber, and modified synthetic rubber, and it is preferable that the microfibrillated plant fibers should be cellulose microfibrils.
