    Abstract: A tire for a wheel of a vehicle includes a carcass, a belt structure, and a tread. The tread pattern includes at least two circumferential grooves and at least three circumferential ribs. The grooves include a zigzag configuration and a shape repeated according to a circumferential pitch. Within a single pitch, each groove includes at least two directions different from a circumferential direction of the tire, generating at least two ground-gripping fronts in each of two rotation directions of the tire, and at least one blind transverse cut extending from opposite sides of the groove, generating a third ground-gripping front. Ends of the blind transverse cuts are positioned on planes parallel to each other and to an equatorial plane of the tire. The first plane and the second plane delimit a continuous portion of at least one of the circumferential ribs. The continuous portion includes a constant axial width.

    Abstract: A pneumatic tire includes main grooves 1 extending substantially in a circumferential direction R of the tire, transverse grooves 2 connecting adjacent main grooves, and blocks 3 formed by adjacent main grooves and adjacent transverse grooves. Each block 3 has an acute corner portion 3a and an obtuse corner portion 3b and also has a groove side extending along the main groove 1 between the acute corner portion 3a and the obtuse corner portion 3b. An inclination angle a1 of the groove side increases from the obtuse corner portion 3b toward the acute corner portion 3a. An extending direction 1a of the main groove 1 at a tread surface level is inclined toward one side of the main groove 1 with respect to the circumferential direction R of the tire, while an extending direction of the main groove 1 at a groove bottom level is inclined toward the other side.

    Abstract: Disclosed is a pneumatic tire effectively controlling uneven wear occurring in the vicinity of a main groove even if a groove width of the main groove is narrowed due to change in tread radius during inflation. In the pneumatic tire, with regard to a zigzag-shaped main groove having the groove width narrowed during inflation among a plurality of main grooves provided on the tread surface, an inclination angle of a groove wall near the shoulder with respect to the tread surface is made relatively large in a bent portion near the shoulder, an inclination angle of a groove wall near the center with respect to the tread surface is made relatively large in a bent portion near the center, and regions where the inclination angles of the opposed groove walls are different from each other are uncontinuously arranged in the tire circumferential direction.

    Abstract: To maintain excellent antiwet skidding performance and good tire external appearance until a radial tire for heavy-duty road vehicles serves its time, a plurality of narrow grooves (40) are formed along at least longitudinal direction of each of plural platforms arranged at intervals in circumferential direction of each of land portions formed between two main circumferential grooves, in order to separate the platform from the tire land portion. This is because the narrow grooves serve to decrease the rigidity of the platforms and therfore to allow the platforms to be more slidably movable relative to the ground to increase abrasion rate on the platform surface, thus maintaining a height difference between the tire land portions and the platforms.

    Abstract: A tread pattern for a pneumatic tire having a plurality of circumferentially extending zig-zag and straight longitudinal grooves and a multiplicity of transverse grooves extending generally axially and joining the longitudinal grooves to define a block pattern.The tread pattern will change from a block pattern to a rib pattern as it wears because the transverse grooves extend to a shallower depth than the longitudinal grooves. The bottom of the longitudinal grooves, which are at a greater depth, preferably have a different zig-zag pattern than the part of the longitudinal groove which contact the road when the tire is new.

    Abstract: A pneumatic vehicle tire having a tread provided with profiled ribs extending continuously in the circumferential direction, and with circumferential continuous grooves which separate the profiled ribs from each other. A plurality of meandering profiled ribs are provided, and their laterally outer side edges have obtuse-angled serrations or toothing. Inwardly, these ribs are provided with linearly extending blind grooves which are oriented at an angle to the circumferential direction. Block-rib parts are formed with an inclined gable embodiment. Furthermore, the circumferential grooves have a zig-zag shape.
