PROBLEM TO BE SOLVED: To obtain an aqueous cement for tires having an improved unvulcanized adhesiveness. SOLUTION: This aqueous cement contains a rubber latex, carbon black which has a nitrogen adsorption specific surface area of 60-200 m2/g and a dibutylphthalate oil absorption of 60-180 ml/100 g, and an adhesiveness-providing resin. The adhesiveness-providing resin is preferably at least one selected from the group consisting of a coumarone-indene resin, a phenol-terpene resin, a petroleum hydrocarbon resin and a rosin resin.
