Obj ectIn racing tires for racing on ice and snow, a tire with stud pins is used to reduce lap time. To allow a tire to track on an icy or snowy road surface, a tread rubber needs to have a certain degree of softness, but a soft tread rubber has a defect that blocks formed on the tread twist in a high-speed and high-load region, and further, that stud pins come off during continuous running.Solving MeansThe above-described problems have been solved by a rubber composition for a studded tire, the rubber composition being obtained by blending 50 parts by mass or more of carbon black per 100 parts by mass of diene rubber and subjected to sulfur vulcanization, the rubber composition containing a monosulfide bond in an amount of from 8 to 18 mass% and having a volume fraction of the carbon black of from 22 to 25%.
