Method of producing tire
Abstract:
There is provided a method of producing a tire comprising the steps of: applying a chafer rubber 21 by spirally winding a rubber ribbon onto a base 15; applying a sidewall rubber 22 of a first color by spirally winding a rubber ribbon at a position on the base 15 spaced from the position where the chafer rubber is stuck; applying a sidewall rubber 23 of the second color by spirally winding a rubber ribbon between the chafer rubber sticking position and the first color sidewall rubber sticking position; and applying a cover rubber 24 of the first color over the entire surface of the sidewall rubber of the second color, wherein on the occasion when said chafer rubbers 21 or sidewall rubbers 23 of the second color are stuck, they are applied so that they are adjacent to each other, thereby sticking a rubber member of a colored tire onto the sidewall of the tire without involving defects such as trapped air and a bare as well as severe decrease of the productivity.
