Abstract:
A method of manufacturing a tire,the tire comprising rubber components, the method comprising a step of making at least one of the rubber components by winding a rubber tape, wherein the rubber tape is provided on each side of a central part with a fin, the central part having a thickness of 0.3 to 1.5 mm, the fin having a substantially constant thickness less than the thickness of the central part and a width of from 0.5 to 5.0 mm, and in a cross section of the rubber tape, the rubber tape has two sides which extend from one of the fins to the other fin defining said central part, said two sides have one of the following designs (1)-(9): (1) one side is a straight line extending in the widthwise direction of the rubber tape, and the other side is a straight line extending in the widthwise direction of the rubber tape between two shorter lines perpendicular to the straight line; (2) one side is a straight line extending in the widthwise direction of the rubber tape, and the other side is a straight line extending in the widthwise direction of the rubber tape between two shorter oblique lines: (3) one side is a straight line extending in the widthwise direction of the rubber tape, and the other side is a straight line extending in the widthwise direction of the rubber tape between a shorter line perpendicular to the straight line, and a shorter oblique line; (4) one side is a straight line extending in the widthwise direction of the rubber tape, and the other side is a curved line in a form of half ellipse; (5) one side is a straight line extending in the widthwise direction of the rubber tape, and the other side is a zigzag line in a form of alphabetic character â€œWâ€ ; (6) each said side is a straight line extending in the widthwise direction of the rubber tape between two shorter lines perpendicular to the straight line; (7) each said side is a straight line extending in the widthwise direction of the rubber tape between a shorter line perpendicular to the straight line and a shorter oblique line, and the positions of the shorter perpendicular line and shorter oblique line of one side is reverse to those of the other side; (8) each said side is a curved line in a form of half ellipse; (9) each said side is a zigzag line in a form of alphabetic character â€œWâ€ the character â€œWâ€  on one side being the reverse of that on the other side.
