PROBLEM TO BE SOLVED: To improve viscoelastic properties of a vulcanized rubber used for production of a tire. SOLUTION: S-(5-aminopentyl)thiosulfuric acid or its metal salt is used for improving viscoelastic properties of the vulcanized rubber. A metal ion in the S-(5-aminopentyl)thiosulfuric acid metal salt is preferably a lithium ion, a sodium ion, a potassium ion, a cesium ion, a cobalt ion, a copper ion, or a zinc ion.
