Vehicle Pneumatic Tires

Abstract

The invention relates to vehicle pneumatic tires having a tread which, observed in the case of tires mounted on the vehicle, has a profile band (1) arranged on the outside shoulder which is separated from additional profile elements by a circumferential groove (2) which extends in the circumferential direction, wherein a plurality of transverse grooves (3), extending at least substantially parallel to each other, is provided in the shoulder-side profile band (1), which groves consist of a plurality of groove sections (4, 5, 6, 6') extending at angles to each other. The transverse grooves in the outside shoulder region are comprised of three groove sections (4, 5, 6, 6'), wherein the two outer groove sections (4, 6, 6') extend at least substantially in the axial direction and the center groove section (5) connecting said outer groove sections extends to the two outer groove sections (4, 6, 6') each at an obtuse angle (β, β'), which equals 135° at maximum, wherein the outer groove sections (4, 6, 6') each have a groove flank (7, 14), extending at least substantially in the axial direction, and a groove flank (7, 14) comprised of a flank section (7'a, 14'a), extending at least substantially in the axial direction, and a bevel (8, 12), wherein the center groove section (5) is formed from two bevels (9, 10), wherein the bevels (8, 12) in the outer groove sections (4, 5, 6, 6') extend to a depth identified in the axial direction which is a specific value, proportional for said bevels (8, 12), of both or the greatest depth (T) of said groove sections (4, 5, 6, 6'), and wherein the bevels (9, 10) which form the center groove section (5) extend to a depth which at least substantially equals the depth of the bevels (8, 12) of the outer groove sections (4, 6, 6') on the corner regions thereof to the center groove section (5).

Description

technical field [0001] The present invention relates to a pneumatic tire for vehicles having a tread having a tread band arranged at the outer shoulder, the tread band passing through a circumferential Circumferential grooves in a direction that are spaced apart from the other tread elements, wherein in the shoulder-side tread band there is provided a plurality of groove segments extending at an angle to one another, at least substantially Transverse grooves extending in parallel. Background technique [0002] A pneumatic vehicle tire of this type is known, for example, from US 5,388,625 A. The tread pattern of this tire has five tread bands running in the circumferential direction which are separated from one another by a plurality of wide circumferential grooves. These three tread bands extending in the middle region of the tread are divided into blocks, which are separated from each other by transverse grooves which are each composed of three sections, namely two A sec...
