Embodiment Construction

[0025] figure 1 A section of a tire crown is shown which is especially suitable for winter tires for passenger cars and which has been specially designed for this purpose. The figure shows some crown elements designed as crown blocks 1 and tangentially forming a sequence of crown blocks through a wide, tangentially encircling tangential groove 2 separated from each other. In each sequence of crown blocks, the crown blocks 1 are separated from each other by transverse grooves 3 . Each crown block has a number (three in the embodiment shown) of depressions 4 extending at least approximately parallel to the transverse grooves 3 and completely traversing the crown block 1 , these depressions substantially the same distance between the recesses and the crown edge delimiting the transverse groove 3 . The depressions 4 shown run in the shape of waves, the waves having a constant amplitude and a constant wavelength. However, the depressions 4 embodied according to the invention ca...

Abstract

The invention relates to a pneumatic air tire having a tread, which is composed of tread elements (1), each being provided with a number of recesses (4) extending in a wave or zigzag-shape viewed from above, and preferably extending substantially in the transverse direction of the tread, wherein the recesses (4) have broader sections (5) about the locations (4a) of the maximum amplitude than in between, and wherein the broadenings are provided on the outside.

Description

technical field [0001] The present invention relates to a pneumatic tire having a crown having a plurality of crown elements, such as crown blocks or crown ribs, having a certain number of depressions, from above Observed, these depressions extend corrugated or zigzag, preferably substantially in the transverse direction of the crown. Background technique [0002] Pneumatic tires with an elongated and depressed crown are specially designed for use in winter driving conditions, and different designs are known. Among them, the depressions are usually designed to extend in a corrugated or zigzag manner. The depressions can completely traverse the crown unit, or can extend over a partial area of ​​the crown unit, and most of them reach a depth corresponding to the predetermined crown depth in the radial direction in the form of segments. Furthermore, it is also known to provide depressions of varying width in the crown. For example US-A-6,681,824 discloses a crown with depres...
