摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of product defects such as a bare state, entry of air and flow cracking by making it possible to verify whether or not a rubber flow is properly performed when a green tire is vulcanization-molded.SOLUTION: A green tire prototyping method is practiced by a first step of forming a pattern, which comprises a plurality of marks 9, in such a manner that the respective marks 9 are aligned in the radial direction of the green tire 1, and a second step of vulcanization-molding the green tire 1 where the pattern is formed.
