<p>PROBLEM TO BE SOLVED: To provide a rubber composition which makes it possible to improve tire performance, particularly rolling resistance, by use of materials with small environmental loads and low costs, and provide a tire with improved tire performance, particularly rolling resistance.SOLUTION: A rubber composition is characterized in that, with respect to 100 pts.mass of a rubber component, 0.2-9 pts.mass of a plant resource-extract residue is contained, and a maximum major axis of the plant resource-extract residue is 50-240μm.</p> |
