To provide a rubber member useful for preventing molding defects as well as improving tire uniformity, and to provide a method for the production thereof and a method of producing tire.

The rubber member for tire is formed by spirally winding an unvulcanized rubber strip S. The rubber member is characterized in that the end part e1 at the winding start side of the rubber strip S has a tilted end edge 10 which extends at a slant viewed from above from one side edge E1 of a top T toward the other side edge E2 of the strip S at an angle of 10 but 80 with respect to the side edge E1.
