Embodiment Construction

[0023] Figure 1 to Figure 4 A tread pattern of a vehicle pneumatic tire for a passenger car (PKW) is shown, the tread pattern having a central portion oriented in the circumferential direction U of the vehicle pneumatic tire and extending over the circumference of the vehicle pneumatic tire Circumferential grooves 3 which divide the tread pattern into two tread halves arranged adjacent to each other in the axial direction A of the vehicle pneumatic tire middle. exist figure 1The tread halves shown on the right are distributed over the circumference of the vehicle pneumatic tire and form rib-shaped, radially raised tread units 2 of known type arranged one behind the other in the circumferential direction U, which The groove units each extend in the axial direction A starting from the circumferential groove 3 to a point in the right shoulder outside the bottom support surface width TA and stop there. The bottom bearing width TA is the width of the part of the tread in cont...

Abstract

The invention relates to a tread profile of a vehicle pneumatic tire having a first fine notch (8) in the primary extension direction in the radial outer surface (10) made of at least one first (12) and one second (13) extension section, designed at a distance h from each other in succession, wherein the first fine notch (8) is designed extending on a common, substantially linear extension line, and from a third extension section (14), formed between said two extension sections (12, 13), which connects the two extension sections (12, 13) and wherein the first fine notch (8) is designed having no further interface along the entire extension thereof, and between the first (12) and the second (13) extension section of the first fine notch (8), an additional second find notch (9) is designed, extending in a linear manner on the common extension line and having a distance to the first fine notch (8).

Description

technical field [0001] The invention relates to a tread pattern of a pneumatic tire for vehicles having radially raised tread elements delimited in the axial direction A by at least two sipe or grooves and having a first thin cut, These first fine cuts delimit respectively in the radially outer surface of such a tread unit a sipe or groove of the tread unit towards one axial side on the one hand and a tread towards the other axial side on the other hand between the grooves or grooves of the unit, wherein the first thin cut in the direction of its main extension in the radially outer surface consists of a first extension section and a second extension section formed one behind the other at a distance h section and is formed by a third extension section formed between these two extension sections, in the first extension section and the second extension section, the first fine cuts are respectively in a substantially straight common Extended on the extension line, the third exte...
