摘要： Both wet weather performance and steering stability performance are achieved.
Lateral main grooves (16) formed in a tread (12) extend in a direction intersecting with circumferential main grooves (14) and open onto the circumferential main grooves (14). Water between the tread (12) and a road surface during wet weather running is accordingly discharged through the lateral main grooves (16) to the circumferential main grooves (14). The end portions of the lateral main grooves (16) opening onto the circumferential main groove (14) are provided with intersection portions 18 where first land portions (21) and second land portions (22) adjacent to each other in the tire circumferential direction at a lateral main groove (16) support each other in the tire width direction. The end portions at the circumferential main groove (14) side of the first land portions (21) and the second land portions (22) do not therefore readily tilt over even when a large slip angle is imparted to the tire.

摘要： A vehicle tire has a tread portion including blocks (10), peripheral grooves (12A, 12D) and transverse grooves (17). Selected blocks (10) are formed with serrations (20). The serrations (20) present a traction surface sloping inward at an angle from the tread surface (11) of the tread portion and intersect the side of a groove above the bottom of the groove.

摘要： A pneumatic tire where the positions of the deepestmost sections (33btm) of circumferential grooves (33) vary in the circumferential direction, at a predetermined cycle in the tread width direction in the circumferential grooves (33). Further, depth direction positions at which the groove bottom surface of a circumferential groove (33) is in contact with perpendicular lines (perpendicular line P1, perpendicular line P2), and in addition, an angle formed by the perpendicular lines and by a cross-sectional line in the width direction of the treads of the groove bottom surface vary at predetermined intervals in the circumferential direction. The perpendicular lines are lines substantially perpendicular to or perpendicular to the surfaces of treads that pass edge sections (edge section 11eg, edge section 12eg) on the circumferential groove side of ribs. In the pneumatic tire, unequal wear of the tire caused by lateral force from the tread width direction is suppressed and wet performance is improved.
摘要翻译：一种充气轮胎，其中周向槽（33）的最深部分（33btm）的位置在周向槽（33）中在胎面宽度方向上以预定周期在周向方向上变化。此外，圆周槽33的槽底面与垂直线（垂直线P1，垂直线P2）接触的深度方向位置以及由垂直线和横截面形成的角度，槽底面的胎面宽度方向的截面线在周向上以规定间隔变化。垂直线是基本垂直于或垂直于通过肋的圆周凹槽侧上的边缘部分（边缘部分11eg，边缘部分12eg）的胎面的表面的线。在充气轮胎中，由来自胎面宽度方向的横向力引起的轮胎的不均匀磨损被抑制，并且湿性能得到改善。

摘要： The invention relates to a vehicle pneumatic tire, particularly for utility vehicles, having a plurality of peripheral grooves (2) running in the peripheral direction, which grooves have outer edges (3) on the tread periphery, which run at least substantially parallel to each other in the peripheral direction and which are at least substantially straight. A groove base path (7) is formed on the groove base and is at least approximately wave-shaped and/or zigzag-shaped, and is narrower than the width of the peripheral groove (2) on the tread periphery. Projections (6) of the groove flanks (5) are assigned to the inward pointing corners of the groove base path (7). The projections (6) are parts or sections of bodies which have a base surface (6a) having at least four free sides. The base surface runs near the tread periphery at an angle (α) of at least 60° and is inclined to the radial direction. The base surface (6a) also has border surfaces (6b, 6c) which run from the free sides in the direction of the groove base at a smaller angle (ß) and which are inclined to the radial direction. Between the projections (6) which are located next to each other in the peripheral direction, two flank surfaces (5a) are provided which run in the direction of the groove base path (7) and which have an angle of inclination to the radial direction which is larger than the angle (ß) of the border surfaces (6b, 6c) and smaller than the angle (α) of the base surfaces (6a).

摘要： A pneumatic tire 1 includes a plurality of main grooves 21 and 22 extending in a tire circumferential direction and at least four ribs 31 to 33 sectioned by the main grooves 21 and 22 on a tread portion. The main groove in the outermost position in a tire width direction out of the main grooves 21 and 22 is an outer main groove 22. Sipes 311 to 332 formed across edge portions of the ribs 31 to 33 on both sides are open sipes. Sipes 323 and 333 formed on the edge portions of the ribs 31 to 33 on one side are multisipes. The open sipes 311 to 332 are formed on the ribs 31 to 33, the multisipes 323 and 333 are formed on only the ribs 32 and 33 between which the external main groove 22, and the multisipes 323 and 333 are aligned along the edge portions of the rib 32 and 33.

摘要： Die Erfindung bezieht sich auf Fahrzeugreifen, insbesondere auf Fahrzeugluftreifen für nicht angetriebene Achsen von Nutzfahrzeugen. In an sich bekannter Weise sollen diese Reifen derartig wellenförmige Längsrillen aufweisen, daß die Wellenamplitude im Nutengrund größer ist als an der Peripherie. Dies wird durch periodisches Verwinden um eine in Umfangsrichtung verlaufende Achse erreicht. Die Wellenamplitude an der Peripherie darf auch gleich Null sein. Um an solchen Reifen das Steinefangen zu vermindern, wird erfindungsgemäß vorgeschlagen, daß die Längsrillen in ihren axial mittleren Bereichen je einen steil zur Umfangsrichtung verlaufenden Versatz aufweisen, während sie in den Extrembereichen in an sich bekannter Weise nur einen spitzen Winkel mit der Umfangsrichtung einschließen.
