    • Provided is a pneumatic tire (1), in which turbulent flow creating ridges (10) extending from the inner circumference side to the outer circumference side are formed at intervals in the tire circumference direction on the outer circumference (3a) or the tire surface of a tire side portion (3). The pneumatic tire is characterized in that the turbulent flow creating ridges (10) have edge portions (10g), as viewed in the sectional shape (or the ridge width section shape) cut in the direction perpendicular to the extending direction, and in that the front wall angle Θ1, which is made between the front wall faces (10a) of the turbulent flow creating ridges (10) to be hit by an air flow and the tire surface (or the outer circumference (3a)), is set within a range of 70°to 110°.

    • A tread of a pneumatic tire is provided to prevent damage of a tread during driving by preventing small stones or foreign matters from being inserted into grooves, and to prevent a car from being slid on a wet road by easily discharging water to side surfaces of the longitudinal grooves. A tread(100) of a pneumatic tire comprises a block(110), a plurality of longitudinal grooves(120) and a groove protrusion(130). The block is plurally formed along an outer circumferential surface of the tire. The plurality of longitudinal grooves partition the block along a driving direction of the tire. The groove protrusion is formed with predetermined distance along both side surfaces of the longitudinal grooves. The groove protrusion has hook shape, and a sharp portion of the hook is faced toward the driving direction of the tire.
    • 提供一种充气轮胎的胎面,以防止在行驶过程中胎面损坏,防止小石块或异物插入槽中,并且通过容易地将水排放到水面的侧面,防止汽车在湿路面上滑动 纵向槽。 充气轮胎的胎面(100)包括块(110),多个纵向槽(120)和槽突起(130)。 沿着轮胎的外周面多个地形成该块。 多个纵向槽沿着轮胎的行进方向分隔该块。 槽突起沿着纵向槽的两个侧表面形成预定的距离。 槽突起具有钩形,钩的锋利部分面向轮胎的行进方向。

    • PURPOSE: A pneumatic tire is provided with improved soundproof performance, and to maintain the drain performance and anti-wear performance. CONSTITUTION: A pneumatic tire comprises a plurality of vertical grooves and one or more land portions on a tread portion. One or more land portions comprise horizontal grooves(10). One end of the horizontal groove is linked to the vertical groove. The other end of the horizontal groove is extended toward a tire equator. The wall surface of the vertical groove comprises a concave portion(11) and a convex surface portion(12). The concave portion is dented toward the tire equator. The convex surface portion protrudes toward the vertical groove from the concave portion. The convex surface portion comprises a main surface(13) and a gentle incline portion(14). The main surface is vertical to the bottom of the groove. The gentle incline portion connects the outer edge of the main surface to the outer edge of the tread portion, and has a gentler slope than the main surface.
    • 目的:充气轮胎具有改进的隔音性能,并保持排水性能和抗磨损性能。 构成:充气轮胎包括多个垂直槽和胎面部分上的一个或多个胎面部分。 一个或多个陆部包括水平凹槽(10)。 水平槽的一端连接到垂直槽。 水平槽的另一端向轮胎赤道延伸。 垂直槽的壁面包括凹部(11)和凸面部(12)。 凹部向轮胎赤道凹陷。 凸面部从凹部向垂直槽突出。 凸表面部分包括主表面(13)和平缓的倾斜部分(14)。 主表面垂直于凹槽的底部。 柔软的倾斜部分将主表面的外边缘与胎面部分的外边缘相连,并且具有比主表面更平缓的倾斜度。
