PROBLEM TO BE SOLVED: To provide a tire capable of suppressing separation at the end of a chafer.SOLUTION: In a method of manufacturing, a process of manufacturing a rubber sheet 15 positioned between a folded-back portion 5B and a chafer end portion 9AE includes the steps of: coagulating a rubber latex before coagulation treatment including carbon black to obtain a coagulation product; adding a compound represented by the formula (I) to the coagulation product containing water; and dispersing the compound in the coagulation product. (Rand Rindependently represent H, an alkyl group with C1-20, an alkenyl group, or an alkynyl group; Mrepresents Na, Kor Li)SELECTED DRAWING: Figure 2
