Provided is a heavy duty tire with an improved drainage performance. According to one embodiment of the present invention, while preventing opening of a cuff and maintaining strength of a block, a water (rainwater, etc.) on a ground is quickly sucked in and drained, so slip resistance is increased. The heavy duty tire with the improved drainage performance according to an embodiment of the present invention comprises: a cuff formed in a shape of a groove which opens toward the outside while going from one side of the block to the other side; a flow path pipe formed inside the cuff; and a cuff unit having equal to or more than one drainage guide pipe which is formed across the cuff and the flow path pipe and guides the water from the ground to the flow path pipe to improve drainage performance.

    본 발명의 일 실시 예는 커프의 벌어짐 방지와 블록의 강도를 유지하면서도 지면의 물(빗물 등)을 신속하게 흡입하여 배수함으로써 미끄럼 저항성을 높여주는 배수성능을 향상시킨 중하중용 타이어를 제공한다. 본 발명의 실시 예에 따른 배수성능을 향상시킨 중하중용 타이어는, 상기 블록의 일측에서 타측을 향해 가면서 외부를 향해 개방되는 홈 형태로 형성되는 커프, 상기 커프의 안쪽에 형성되는 유로관, 및 상기 커프와 상기 유로관에 걸쳐 형성되어 지면의 물을 상기 유로관으로 유도하여 배수성능을 향상하는 하나 이상의 배수유도관을 구비하는 커프부;를 포함한다.
