Claims (10)

  1. 탄성 중합체물질과, 접지 탄성중합체 요소를 규정하는 복수개의 그루브를 포함하는 것으로서, 상기 접지요소는 폭, 길이 및 깊이를 갖는 사이프를 구비하고 있는 타이어 트레드에 있어서, 상기 접지 요소중 적어도 하나는 상기 트레드의 표면으로부터 상기 탄성 중합체물질의 내부를 향해서 연장된 제1의 절개부를 가지며, 상기 제1의 절개부는 상기 트레드 표면으로부터 멀어지는 방향으로 연장된 적어도 2개의 절개부로 분할되어 있고, 상기 절개부들은 그들이 갖는 깊이의 적어도 일부에 걸쳐서 서로에 대하여 벌어져 있는 것을 특징으로 하는 타이어 트레드.
  2. 제1항에 있어서, 상기 절개부중 적어도 2개는 그들의 절체 깊이에 걸쳐서 연속적으로 벌어져 있는 것을 특징으로 하는 타이어 트레드.
  3. 제1항에 있어서, 상기 절개부중 적어도 2개는 동일한 깊이로 연장되어 있는 것을 특징으로 하는 타이어 트레드.
  4. 제1항에 있어서, 상기 절개부중 적어도 2개는 동일한 길이를 갖는 것을 특징으로 하는 타이어 트레드.

  7. 제1항에 있어서, 상기 제1의 절개부는 그것을 통과하는 반경방향 연장선에 대하여 0°내지 30°의 각도를 이루는 평면상에 놓여있는 것을 특징으로 하는 타이어 트레드.
  8. 제1항에 있어서, 상기 절개부중 적어도 하나의 일부는 폭을 거의 갖지 않는 것을 특징으로 하는 타이어 트레드.
  9. 제1항에 있어서, 상기 제1의 절개부와 상기 절개부들중 일부의 반경방향 길이를 합한 값은 상기 그루브의 길이와 대략 동일한 것을 특징으로 하는 타이어 트레드.
  10. 제1항에 있어서, 상기 절개부중 적어도 하나는, 서로에 대하여 점차 벌어져 있고 상기 트레드 표면으로 부터 멀어지는 방향으로 연장된 2개의 또다른 절개부로 분할되어 있는 것을 특징으로 하는 타이어 트레드.
