The present invention relates to a pneumatic tire comprising: a tread part; a side wall part; and a bead part. A carcass is turned up and installed on the bead part. Multiple belt layers are stacked and installed between the carcass and the tread part. A full cover reinforcement belt and an edge cover belt are installed on the uppermost part of the belt layers. The edge cover reinforcement belt has EPI 5-15% increased and a cord section area 10-20% increased compared with the full cover reinforcement belt. The edge cover reinforcement belt has high-speed durability improved by providing tensile strength increased compared with the full cover reinforcement belt (8a), and greatly reducing a standing wave phenomenon on a side part during high-speed driving.

    본 발명은 트레드부와 사이드월부 및 비드부를 포함하며, 상기 비드부에 카카스가 턴업 설치되고, 카카스와 트레드부 사이에 복수의 벨트층이 적층 설치되며, 상기 벨트층의 최상부에는 풀커버 보강벨트와 에지커버 보강벨트가 설치되고, 상기 에지커버 보강벨트는 풀커버 보강벨트에 비하여 EPI가 5~15%, 코드 단면적이 10~20% 증가되는 공기입 타이어에 관한 것으로, 에지커버 보강벨트가 풀커버 보강벨트(8a)에 비하여 증가된 인장 강도를 가짐으로써 고속주행 시 사이드부의 스탠딩 웨이브 현상을 크게 감소시켜 고속내구성이 향상되는 효과가 있다.
