Problems solved by technology

In the case of cuts in which the two edge sections are raised at different heights, the visual appearance changes section by section during wear, such cutouts result in different circumferential stiffnesses over the width of the tread block, since the edge sections have a shallower depth, the tread blocks are harder, which leads to different edge characteristics during coasting (Latschdurchlauf) and cause snow performance to suffer

Embodiment Construction

[0049] The invention consists of a special arrangement of cut-outs in the tread of passenger car (PKW) tires, which tires are particularly suitable for use in winter driving conditions.

[0050] figure 1 Shows an example, direction-of-travel-bound (laufrichtungsgebunden) of the circumferential section of the realized tread stripe, which is located on each tread half Center, with one wide row of blocks 1 on the shoulder side and two other central rows of blocks 2 in the middle of the tread. Each row 1 of blocks has blocks 3 separated from one another by transverse grooves 5 running substantially transversely of the tread. Each central block row 2 , which is separated from the adjacent shoulder-side row 1 by a circumferentially surrounding circumferential groove 10 , has tread blocks 4 and transverse grooves 6 , which In the embodiment shown, the groove runs in the extension of the transverse groove 5 . The central row of blocks 2 is delimited at a central circumferential gr...

Abstract

The invention relates to a vehicle tire, in particular for use in winter driving conditions, comprising a tire tread having at least one tread bar row (2) extending all-round in a circumferential direction, the tread bars (4) thereof having tread bar edges (4b) which delimit transverse grooves (6) which separate the individual tread bars (4) from each other within the tread bar row (2), wherein the tread bars (4) each have at least two at least substantially parallel notches (7), the extensions of which in the respective tread bar (4) are oriented on the basis of the progression of the tread bar edges (4b) delimiting the transverse grooves (6) and which notches (7) have a center section and two edge sections, wherein the center section is the deepest and longest section and the two edge sections have differing depths. At least the center section (7b) of those notches (7) which run adjacent to the tread bar edges (4b) that delimit the transverse grooves (6) include an acute angle with said tread bar edge (4b), wherein the edge section having a lower depth connects to the end of the center section which has the smaller distance to the adjacent tread bar edge (4b, 4'b).

Description

technical field [0001] The invention relates to a vehicle pneumatic tire, in particular a vehicle pneumatic tire for winter driving conditions, which has a tread with at least one row of blocks running around in the circumferential direction, the tire The blocks of the row of blocks have block edges which define transverse grooves which separate the individual blocks within the row of blocks from one another, wherein the blocks each have at least approximately at least two incisions running parallel to each other, the extension of the incisions in the respective tread block towards the course of the edge of the block delimiting the transverse grooves, and the incisions have a middle section and two edges sections, wherein the middle section is the deepest section, and the two edge sections have different depths. Background technique [0002] It is known and common that pneumatic vehicle tires for winter driving conditions are provided with lugs on the tread, which lugs each...
