## Abstract

Pneumatic vehicle tire having sidewalls and having at least one hatching area (1) or a hatched area element on at least one sidewall, wherein the hatching area (1) or the area element has a multiplicity of hatching ribs (2, 2′, 2″) running next to one another and having two lateral flanks (3a, 3′a, 3″a, 3b, 3′b, 3″b). The one lateral flank (3a, 3′a, 3″a) of the hatching ribs (2, 2′, 2″) has a surface finish which differs from that on the other lateral flank (3b, 3′b, 3″b) of the hatching ribs (2, 2′, 2″).

## Claims

### Claim 1

A pneumatic vehicle tire, comprising:
sidewalls, and
at least one hatching area or a hatched area element on at least one of the sidewalls,
wherein the hatching area or the area element has a multiplicity of hatching ribs running next to one another,
wherein each of the multiplicity of hatching ribs has two lateral flanks,
wherein, of the two lateral flanks, a first lateral flank has a first surface finish that differs from a second surface finish on a second lateral flank of the hatching ribs,
wherein at least the first surface finish includes a three-dimensional structure,
wherein the three-dimensional structure covers an entire lengthwise extent of each respective first lateral flank on which the three-dimensional structure is applied,
wherein the three-dimensional structure includes a multiplicity of additional ribs that are parallel to one another and at right angles to the extent of the hatching ribs,
wherein each of the multiplicity of additional ribs extends along; an entire height of the first lateral flank from a tip of the first lateral flank to a base of the first lateral flank.

### Claim 2 (depends on 1)

The pneumatic vehicle tire as claimed in claim 1, wherein when the hatching ribs running next to one another are viewed, the first lateral flank of the hatching rib comprising the first surface finish is facing a further lateral flank of an adjacent hatching rib comprising the second surface finish.

### Claim 3 (depends on 1)

The pneumatic vehicle tire as claimed in claim 1, wherein the additional ribs are formed by a multiplicity of elevations and depressions formed directly next to one another, the elevations having a height of 0.05 mm to 0.8 mm, and the depressions having a depth of 0.05 mm to 0.8 mm.

### Claim 4 (depends on 1)

The pneumatic vehicle tire as claimed in claim 1, wherein the additional ribs have a width (b2) at their base of 0.1 mm to 0.5 mm.

### Claim 5 (depends on 1)

The pneumatic vehicle tire as claimed in claim 1, wherein the hatching ribs, viewed in cross section, are triangular.

### Claim 6 (depends on 5)

The pneumatic vehicle tire as claimed in claim 5, wherein the first lateral flank of the hatching ribs runs at a first angle of 5° to 60° in relation to a line normal the sidewall and the second lateral flank runs at a second angle that is larger than the first angle by at least 5° in relation to a line normal the sidewall.

### Claim 7 (depends on 6)

The pneumatic vehicle tire as claimed in claim 6, wherein the second angle is 30° larger than the first angle.

### Claim 8 (depends on 1)

The pneumatic vehicle tire as claimed in claim 1, wherein the hatching ribs are provided with dome-like projections thereon having a height (h2) of 0.1 mm to 0.3 mm.

### Claim 9 (depends on 1)

The pneumatic vehicle tire as claimed in claim 1, wherein the additional ribs, viewed in cross section, are triangular.

### Claim 10 (depends on 9)

The pneumatic vehicle tire as claimed in claim 9, wherein the additional ribs are evenly spaced apart from one another along the entire lengthwise extent of the first lateral flank.

### Claim 11 (depends on 1)

The pneumatic vehicle tire as claimed in claim 1, wherein the additional ribs directly adjoin one another.

### Claim 12 (depends on 1)

The pneumatic tire according to claim 1,
wherein the additional ribs are evenly spaced apart from one another along the entire lengthwise extent of the first flank.

### Claim 13 (depends on 12)

The pneumatic tire according to claim 12,
wherein the additional ribs have a width at their base of 0.1 mm to 0.5 mm.

### Claim 14 (depends on 13)

The pneumatic tire according to claim 13,
wherein the additional ribs are triangular.
