The present invention addresses the problem of providing: a rubber composition for a nail-free anti-skid tire, which is capable of improving on-ice performance; and a nail-free anti-skid tire which uses the rubber composition. The tread rubber composition for a nail-free anti-skid tire is characterized by containing a rubber component that contains an isoprene rubber and a conjugated diene polymer, water-soluble fine particles, a hydrocarbon resin and a liquid plasticizer, satisfying the relationship represented by formula (I): the content of the liquid plasticizer + the content of the hydrocarbon resin)/the content of the liquid plasticizer > 1.2 (I).

    本发明的课题在于提供一种能够改善冰上性能的无钉防滑轮胎用橡胶组合物和使用该橡胶组合物的无钉防滑轮胎。一种无钉防滑轮胎用胎面橡胶组合物,其特征在于包含:含有异戊二烯系橡胶和共轭二烯系聚合物的橡胶成分、水溶性微粒、烃类树脂和液体增塑剂,满足下述式(I)的关系。{(液体增塑剂的含量+烃类树脂的含量)/液体增塑剂的含量}>1.2(I)。
