Provided is an undertread rubber composition, which is improved in a blow-out property by using 1,3-bis(citracoimidomethyl)benzene and a fatty acid metal salt and has rheometer and tensile properties equal to or more excellent than the conventional rubber. The undertread rubber composition comprises 1-3 parts by weight of 1,3-bis(citracoimidomethyl)benzene and 1-3 parts by weight of a fatty acid metal salt. The fatty acid metal salt includes at least any one fatty acid selected from acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, enanthic acid, caprylic acid, perargonic acid, capric acid, undecylic acid, lauric acid, tridecylic acid, myristic acid, pentadecylic acid, parchymic acid, heptadecylic acid, nonadecanic acid, archidic acid, acrylic acid, crotonic acid, undecyleic acid, oleic acid, setreic acid, ercaic acid, brush ginic acid, sorbic acid, linolic acid, linoleic acid, and arachidonic acid, and at least one metal selected from zinc and potassium.
