PROBLEM TO BE SOLVED: To obtain a rubber composition containing a reclaimed rubber which can maintain high breakage characteristics without detriment to processability unlike conventional reclaimed rubbers and powdered rubbers and can promote recycling of a rubber product such as a used tire. SOLUTION: The rubber composition containing a reclaimed rubber contains a reclaimed rubber which is obtained by subjecting a powdered rubber, which is prepared by a particle size-micronizing treatment so as to contain at least 25% of particles passing through a 145-mesh screen, to an oil pan method treatment. A tire is obtained by applying the rubber composition. COPYRIGHT: (C)2004,JPO
