The rubber composition for a tire contains fine particles of rotaxane having a straight chain molecule, acyclic molecule clathrating the straight chain molecule and blocking groups arranged at both terminals of the straight chain molecule such that the cyclic molecule does not desorb from the straight chain molecule, covered with silica; a rubber component comprising styrene-butadiene rubber; and at least one of carbon black and silica, wherein the total content of the fine particles, the carbon black and the silica (excluding silica covering rotaxane) is 70 to 150 parts by mass per 100 parts by mass of the rubber component.",
