Provided are: an organopolysiloxane capable of achieving intended low fuel consumption properties and significantly reducing hysteresis loss in the cured product of a rubber composition during tire production; a rubber compounding agent comprising said organopolysiloxane; a rubber composition obtained by blending said rubber compounding agent; and a tire formed using said rubber composition. The organopolysiloxane, which is represented by average compositional formula (1), is characterized in: containing an organic group with a sulfide group; and the sulfide equivalents being 1,000 g/mol or less. (A) a (B) b (C) c (R 1 ) d SiO (4-2a-b-c-d)/2 (1) (In the formula, A is a sulfide group-containing divalent organic group, B is a C5 to C10 monovalent hydrocarbon group, C is a hydrolyzable group and/or a hydroxyl group, R 1 is a C1 to C4 monovalent hydrocarbon group, and for a, b, c and d, 0 < 2a < 1, 0 < b < 1, 0 < c < 3, 0 ¤ d < 2, and 0 < 2a+b+c+d < 4.)
