Problems solved by technology

While this improves grip in winter road conditions, it impedes the drainage of water and therefore may worsen the flotation characteristics
In the case of this configuration, over the life of the vehicle's pneumatic tire, in the event of a drastic reduction in the containment volume of water, snow or slush caused by wear, whether fine cuts or gripping edges created by staggered placement will be reduced

Embodiment Construction

[0064] figure 1 A rotationally bound tread profile of a vehicle pneumatic tire for winter-suitable passenger vehicle tires is shown. This is done in a known manner by (in figure 1 A shoulder profile block row 1 , a profile rib 2 , a profile rib 3 and a shoulder profile block row 4 arranged axially adjacent to each other from left to right in the illustrated embodiment form . The shoulder profile block row 1 is arranged in such a manner that it extends along the circumferential direction U of the vehicle pneumatic tire on the circumference of the vehicle pneumatic tire, is arranged in such a manner that it is successively dispersed on the circumference, and passes through one transverse groove respectively 21 and a plurality of profile block elements 11 arranged in a manner separate from each other are formed in a known manner. The shoulder profile block rows 4 are arranged in such a manner as to extend in the circumferential direction U on the circumference of the vehicle...

Abstract

The invention relates to motor vehicle pneumatic tires having profiled treads with profile elements (11, 14) separated by grooves (21, 24), wherein the grooves (21, 24) exhibit groove walls and form the flanks (8, 9) of a profile element, respectively, wherein at least one flank (8) exhibits a recess (10) that extends into the profile element (14) in a radial interior extension region, said recess exhibiting a sectional contour in the groove wall with v- or u-shaped sides (15, 16) extending in the extension direction of the groove (24), wherein the two sides (15, 16) form a first corner at the intersection (A) thereof and the two other end points (B, C) of the sides (15, 16) are connected to each other by another, particularly a straight, contour line (17).

Description

technical field [0001] The invention relates to a pneumatic vehicle tire having a profiled tread having profile elements separated from each other by sipe, in particular profile block elements of a profile block row , wherein the grooves have groove walls which protrude radially outward from the groove base to the radially further outer profile cover and each form a side wall of a profile element. Background technique [0002] Such pneumatic tires for vehicles are well known. In the case of this known pneumatic tire for vehicles, the grooves with grooved walls are formed by continuing flat surfaces in order not to impede drainage. In winter road conditions, this reduces the number of effective grip edges for generating lateral grip. Over the life of the vehicle's pneumatic tire, the effect of the fine cuts is also reduced by wear, thus additionally reducing the grip effect in winter road conditions. In order to enable sufficient rigidity of the profiled block element, the...
