Abstract

본 발명은 사이드월의 표면불량을 방지한 공기입 레디알 타이어에 관한 것으로, 소정크기로 재단한 후 성형드럼(4)상에서 그 양단부가 서로 겹쳐지게 감아 붙인 카카스(1)의 상ㆍ하측 오버랩부(2)(3) 중 상측오버랩부(2)의 표면에 등간격의 절개선(5)을 다수개 형성하여 1차 성형한 다음 통상의 방법에 따라 타이어를 제조함으로써, 사이드월의 표면불량(Indentation)을 제거할 수 있으며, 타이어의 외관품질 향상 및 타이어 제조회사의 이미지 향상을 꾀할 수 있게 된다.The present invention relates to an air-inlet radial tire for preventing a surface defect of a sidewall, and more particularly, to an air-inlet radial tire which is cut to a predetermined size and then is wound on a forming drum (4) (2) By forming a plurality of equally spaced sections 5 on the surface of the upper overlapping portion 2 and forming the tire by a conventional method, the surface defects of the side walls Indentation can be removed, and the appearance of the tire can be improved and the image of the tire manufacturer can be improved.
