The problem addressed by the present invention is to provide a rubber composition which has a low environmental burden and can improve the on-ice performance of a tire. A solution to this problem is a rubber composition comprising: a rubber component comprising a diene-based rubber; an inorganic foaming agent; and a foaming aid, and is characterized in that the total content of the inorganic foaming agent and the foaming aid is 1-20 parts by mass with respect to 100 parts by mass of the rubber component, and the mass ratio (inorganic foaming agent: foaming aid) between the inorganic foaming agent and the foaming aid is 1: 1.1 to 1: 3.3.

    本发明解决的问题为提供一种具有低的环境负荷并可以改善轮胎的冰上性能的橡胶组合物。该问题的解决方案为一种橡胶组合物,其包括:包含二烯系橡胶的橡胶组分;无机发泡剂;和发泡助剂,并且其特征在于,相对于100质量份的所述橡胶组分,所述无机发泡剂和所述发泡助剂的总含量为1~20质量份,并且所述无机发泡剂和所述发泡助剂之间的质量比(无机发泡剂:发泡助剂)为1:1.1至1:3.3。
