Field of the Invention The present invention relates to a surface treatment method of a mold for manufacturing a high drainage tire. More particularly, the polishing and groove drainage of the mold for forming a tread pattern of the tire are polished to improve performance and drainage performance during driving. The present invention relates to a surface treatment method of a mold for producing a high drainage tire that can produce excellent tires.
일반적으로 타이어의 표면에는 우수한 접지력을 확보하기 위하여 다양한 트래드 패턴(tread pattern)을 형성한다. 타이어는 트래드 패턴의 원주방향으로 배치되어 형성되는 복수개의 그루브(groove)와 폭방향으로 배치되어 형성되는 복수개의 그루브(groove) 형상에 따라 주행시의 성능, 배수 성능, 제동거리에 차이가 있다.In general, various tread patterns are formed on the surface of the tire to secure excellent grip. The tire has a difference in performance, drainage performance, and braking distance when driving, depending on a plurality of grooves formed in the circumferential direction of the tread pattern and a plurality of grooves formed in the width direction.
