An object of the present disclosure is to provide a rubber composition having a low environmental impact and capable of reliably improving the on-ice performance of a tire. To achieve the object, the present disclosure provides a rubber composition, comprising: a rubber component containing diene rubber; an inorganic blowing agent; and a blowing aid, wherein the total content of the inorganic blowing agent and the blowing aid is in the range of 1 to 20 parts by mass with respect to 100 parts by mass of the rubber component, and a mass ratio of the inorganic blowing agent with respect to the blowing aid (the inorganic blowing agent: the blowing aid) is in the range of 1 : 1.1 to 1 : 3.3.
