The tire manufacturing method includes: a master batch was prepared, and a rubber composition and a green tire were prepared from the master batch. The process for producing a master batch includes: coagulating a rubber latex containing carbon black before coagulation treatment to obtain a coagulum, adding a compound of formula (I) to the water-containing coagulum, and dispersing the compound of formula (I) in the coagulum. The green tire is provided with a bead filler, a carcass ply, a chafer, and an unvulcanized rubber sheet made of a rubber composition, wherein the carcass ply includes a folded portion located on the outer side in the tire width direction of the bead filler, the chafer includes a chafer end located on the outer side in the tire width direction of the folded portion, and the unvulcanized rubber sheet includes a connecting portion located between the folded portion and the chafer end. R 1 And R 2 Represents a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 1 to 20 carbon atoms or an alkynyl group having 1 to 20 carbon atoms. R 1 And R 2 May be the same or different. M + Represents sodium ion, potassium ion or lithium ion. |
