    Abstract: A vehicle tire of a radial carcass construction with a low cross-sectional profile having a tread portion that is reinforced by a belt layer is provided. The tread portion comprises two circumferential tread element bands in a center portion of the tire tread and a respective tread element row on the shoulder portion. The tread element bands are separated from one another and from the tread element rows in an axial direction of the vehicle tire by respective wide and deep circumferential grooves that have straight edges. The tread element bands have notches that are distributed in a circumferential direction of the vehicle tire and are oriented at a slant relative to a center plane of the vehicle tire. The notches begin at the circumferential grooves and end within the tread element bands. The tread element rows comprise transverse tread elements that are separated from one another by continuous transverse grooves and are arranged transverse relative to the tread element bands.The tread element bands are provided with narrow grooves that are distributed in the circumferential direction, spaced relative to one another by twice a circumferential length of a tread element repeating unit, defined by the shoulder tread elements and are slanted at a first angle relative to the center plane. The narrow grooves are essentially as deep and 1/4 to 1/3 as wide as the circumferential grooves. The transverse grooves each have a bent portion in the vicinity of the circumferential grooves, whereby the bent portion is oriented at a second angle relative to the center plane, whereby the second angle is greater than the first angle of the narrow grooves.

    Abstract: There is disclosed tires for motor vehicles each having a tread provided with a plurality of large convex portions and small convex portions, the convex portions and the small convex portions being differentiated in heights and areas thereof, the small convex portions being disposed around the large convex portion for forming a plurality of normal pyramidal structures. The normal pyramidal structures are formed by disposing the large concave portion around the small concave portion. There is formed a reversed pyramidal structure by disposing the large convex portions around the small convex portion.

    Abstract: An all season type tire tread (11) comprises a plurality of laterally extending grooves (36) having curved portions adjacent to each lateral edge (TE1, TE2) of the tread, said curved portions extending in circumferentially opposite directions. Axially spaced zig-zag shaped grooves (4-8) extend circumferentially around the tread, every fourth leg of a zig-zag groove being coincident with a portion of a laterally extending groove (36). Two legs adjacent to said fourth leg connect the laterally extending grooves to short semi-blind grooves (19) having their central portion coincident with every other fourth leg of the zig-zag shaped groove. The various grooves cooperate to define block elements (20-25), arranged in circumferential rows (30-35) and having the shape of an "S" or of a "Z". The blocks can include a plurality of slots (50-53) and humps (29) can be located between neighboring blocks.

    Abstract: A pneumatic tire having a tread pattern in which one or more approximately straight longitudinal grooves extending to the circumferential direction of the tire are provided in the tread at a distance (h) from the tire equator to the center of said groove within the range of not more than 2/3 time the distance (H) between the tire equator and the tread edge, said longitudinal groove being composed of repeatedly formed portions each of which has a shape such that the groove width in the tire axial direction between the opposed groove walls varies along the circumferential direction of the tire, whereby the longitudinal grooves, especially those positioned at the center portion of the tread, are prevented from biting small stones without decreasing the wet grip performance of the tire.
