Beschreibung
Zusammenfassung:	A pneumatic tire of the present invention comprises an annular tread portion including a plurality of circumferentially extending main grooves comprising an innermost groove, an outermost groove, and at least one middle groove arranged between the innermost groove and the outermost groove. The outermost groove comprises an inner sidewall, an outer sidewall, a groove bottom, and a groove opening opposite to the groove bottom, wherein the outermost groove has an asymmetric cross section with respect to any straight line perpendicular to the groove opening, and wherein the outer sidewall of the outermost groove is tilted at an angle of more than 20 degrees with respect to a straight line perpendicular to the groove opening. 본 발명의 공기 타이어는, 최내측 홈, 최외측 홈, 및 상기 최내측 홈과 최외측 홈의 사이에 배치된 적어도 하나의 중간 홈을 구비하는 복수의 원주방향 연장형 주 홈을 포함하는 환상의 트레드부를 포함한다. 상기 최외측 홈은 내측 측벽, 외측 측벽, 홈 바닥부 및 상기 홈 바닥부에 대향하는 홈 개구를 구비한다. 상기 최외측 홈은 상기 홈 개구에 수직인 임의의 직선에 대하여 비대칭 단면을 가지며, 상기 최외측 홈의 외측 측벽은 상기 홈 개구에 수직인 직선에 대하여 20°를 초과하여 경사진다.
