Embodiment Construction

[0032] figure 1 A three-dimensional view of a tread profile 1 of a vehicle tire with sipes 2 in profile bands 3 is shown. Each contour band 3 is delimited on both sides by circumferential grooves 4 . The sipes 2 extend through the contour band 3 in an axial direction aR. The sipe 2 has, in a plan view, an approximately Ω-shaped or mushroom-shaped geometry consisting of two axial sections 5 , 6 and a central projection 7 , which are arranged approximately at On a common imaginary straight line in the axial direction aR and at a distance a from each other, the central projection is arranged between the segments 5 , 6 and is oriented approximately in a circumferential direction uR and has an axis The maximum degree b measured in direction aR, where a

Abstract

The invention relates to a running strip profile (1) for a vehicle tyre having fine recesses (2), which have an omega-shaped geometry when viewed from above, consisting of two axial sections (5, 6) and a central protrusion (7) arranged between said axial sections (5, 6), wherein the protrusion (7) forms undercuts (10); the maximum extent (c) of the protrusion is reduced continuously over the depth profile of the fine recess (2) in such a manner that the two axial sections (5, 6) and the protrusion are arranged on a straight line in the fine recess bottom (8).

Description

technical field [0001] The invention relates to a tread profile of a vehicle tire having a plurality of profile fronts, such as profile blocks or tread bands, which have sipes, wherein the sipes have a Roughly Ω-shaped geometry in view: [0002] - having two axial sections which are arranged approximately in one axial direction and at a distance a from one another on a common imaginary straight line, [0003] - has a central projection arranged between said axial sections, wherein the projection has a maximum extent b in the axial direction, and [0004] - where a<b such that multiple lower cuts are formed. Background technique [0005] Sipes are used, for example in the case of utility vehicle tires, to break up the water film in wet road conditions in order to achieve improved wet properties of the tread. [0006] In the case of passenger motor vehicle tires, these sipes are formed in vehicle tires for use in winter driving conditions and are used, for example, by pr...
