~The present invention discloses a tire including an improved sipe. The tire including an improved sipe according to the present invention includes a sipe having fine grooves oriented in a direction that is parallel to a travel direction of a tire or at different angles to secure a ground force on a road surface on which a vehicle travels or a water draining performance on a wet road surface. The sipe includes first and second protruding blocks on first and second side wall surfaces that constitute the fine grooves. The first protruding block and the second side wall surface that is opposite to the first protruding block and the second protruding block and the first side wall surface that is opposite to the second protruding block form a variable water draining space that changes a space for drainage. Accordingly, a strength of the block of the tread may be improved by a new structure of the conventional sipe, water draining performance or snow performance may be improved by shortening a braking distance and optimizing an edge effect, wearing performance and mileage may be improved by deriving a uniform ground area.

    본 발명은 개선된 사이프를 구비한 타이어를 개시한다. 본 발명에 따르는 개선된 사이프를 구비한 타이어는 트레드부에 타이어 진행방향에 따라 평행한 방향이나 다른 각도로 배향되어 형성되는 세홈으로 구비되어 차량이 주행하는 노면에 접지력이나 젖은 노면에서 배수성능을 확보하는 사이프를 포함하는 타이어에 있어서, 상기 사이프는 세홈을 이루는 대향하는 1,2측벽면에 각각 1,2돌출블럭을 구비하며, 상기 1돌출블럭과 이에 대향하는 2측벽면부, 2돌출블럭과 이에 대향하는 1측벽면부는 배수하는 공간을 변화시키는 가변배수공간을 형성하는 것을 특징으로 하는데, 이에 의할 때, 종래의 사이프의 구조를 새롭게 제안하여 트레드부의 블록이 갖는 강성을 향상시키고 제동거리 단축 및 에지 효과를 최적화시켜 배수성능이나 스노우성능을 향상시키며 균일한 접지면적을 유도하여 마모성능 및 마일리지를 향상시킬 수 있다.
