Definitions
- the invention relates to a pneumatic vehicle tire with side walls and a tread strip with at least one shoulder-side profile rib delimited by a circumferential groove with a rib outer surface and a shoulder flank running towards the respective side wall, the shoulder-side profile rib being provided with depressions which emanate from the shoulder flank and an opening on the rib outer surface have, wherein the opening on the inside of the tread strip is delimited by a first boundary edge lying completely within the shoulder-side profile rib and by two second boundary edges in the circumferential direction, and wherein the opening between the second boundary edges in the circumferential direction has a width with a maximum value of 10.0 mm to 30.0 mm.
- Such a tire designed as a commercial vehicle tire is known, for example, from JP 514 411 6 B2.
- the commercial vehicle tire has a tread with two profile ribs on the shoulder, which are each provided with depressions starting from the shoulder flanks and opening towards the outer surface of the rib.
- the indentations are delimited by a slightly S-shaped curved base which merges into the outer surface of the ribs without kinks.
- the indentations have a narrow, elongated shape in the circumferential direction, each determined at the level of the outer surface of the ribs having a width of up to 10 mm in the axial direction and a length of up to 25 mm in the circumferential direction.
- the tire should be suitable for driving on both paved roads and unpaved roads.
- the indentations formed on the shoulder flanks contribute to the traction properties to improve on wet, snowy, sandy, gravelly and muddy surfaces. Furthermore, the indentations have a cooling effect on the professional ribs on the shoulders, which reduces the risk of tire damage. The latter is particularly relevant in the summer months when the asphalt is heated up accordingly. When designing the indentations, it is particularly important to ensure that the surfaces delimiting the indentations are crack-resistant and that no stones can get caught in the indentations.
- the object of the invention is to further improve the cooling effect of the indentations in a pneumatic vehicle tire of the type mentioned at the outset, with the area of the indentations continuing to have high crack resistance and the probability of stone entrapment being low.

- the cooling effect is significantly improved by the elongated opening on the outer surface of the ribs.
- the specially angled or curved floor sections of the floor are particularly favorable for crack resistance. Due to the steep end flank, the probability of stone entanglement is extremely low.
- the width of the opening of the depression decreases continuously towards the inside of the tread, so that the width has its maximum value at the ends of the second boundary edges on the outside of the tread and its minimum value at the ends of the second boundary edges on the inside of the tread. Above all, this contributes to the fact that the probability of stones getting caught in the depressions is further reduced.
- the minimum value of the width is 40% to 60%, in particular 45% to 55%, of the maximum value of the width. This is particularly advantageous for the cooling effect, while at the same time the probability of stone entanglement is low.
- the opening of the recess has a maximum length projected in the axial direction determined at the level of the outer surface of the ribs of 30% to 50%, preferably 40% to 45%, of the maximum length projected in the axial direction determined at the level of the outer surface of the ribs Width of the shoulder-side profile rib.

- a further preferred embodiment is characterized in that the constant depth at which the inside floor section runs is 50% to 80%, in particular 55% to 75%, preferably 60% to 70% of the profile depth. As a result, a good cooling effect of the indentation is maintained via the abrasion of the profile rib on the shoulder.

- Such an inclined end flank also contributes to a reduction in the likelihood of stone entanglement.
- the angle at which the outside base section extends to the radial direction, viewed in the cross section oriented perpendicularly to the first boundary edge in a plan view is 45° to 55°. This configuration contributes to maintaining a high resistance to cracking in the area of the indentation.

This measure also contributes to maintaining a high level of crack resistance in the area of the indentation.

- the indentation is therefore made correspondingly deep at its outside end, which is of further advantage in particular for the cooling effect.
- the recess has side surfaces extending from the second boundary edges, which, viewed in a cross section oriented perpendicularly to the associated second boundary edge, are at an angle of 8° to 25° to the radial direction , in particular from 10° to 15°.
- a further preferred embodiment is characterized in that the shoulder-side circumferential groove, viewed in plan, runs in a zigzag shape and is composed of groove sections which are each at an angle of 15° to 30°, in particular 20° to 25°, to the circumferential direction , Run, wherein the shoulder-side circumferential groove has a kick point with a bend inside and a bend outside at the mutual connection areas of the groove sections, with the depressions each being located axially to the side of a bend inside.
