PROBLEM TO BE SOLVED: To provide a rubber extrusion object making it possible to easily discriminate a direction of the rubber extrusion object with respect to a tire molding drum.SOLUTION: A rubber extrusion object 1 for forming a green tire by being wound on a tire molding drum is extruded in a cross section perpendicular to an extrusion direction X so that a thickness distribution is asymmetric with respect to a center line CL in a width direction Y. A groove 2 that is continuous in the extrusion direction X and used to discriminate a direction of the rubber extrusion object 1 with respect to the tire molding drum is formed on one side 3 in the width direction Y which is separated by the center line CL.
