Embodiment Construction

[0029] figure 1 Shown is a tread pattern of a vehicle pneumatic tire for a passenger car, wherein, in a conventional manner, a plurality of radially raised tread bands are arranged adjacent to each other in the axial direction A of the vehicle pneumatic tire, the tread bands being respectively at The vehicle pneumatic tire extends over the entire circumference and is aligned in the circumferential direction U. In this case, the tread bands 31 or 32 are respectively arranged in each of the two tire shoulders, and the tread bands formed as circumferential ribs 1, 33 and 34 are axially arranged in the two tire shoulders. between the shoulders. The two lug bands 31 and 32 are, for example, block rows of the known type, in which case the block units arranged one behind the other in the circumferential direction are separated from each other in the circumferential direction U by transverse grooves extending transversely. The circumferential ribs 1 , 33 and 34 are known types of c...

Abstract

Tread profile of a vehicle tyre with at least one circumferential rib (1), wherein transversely running grooves (4, 4') are formed in the circumferential rib (1), said grooves extending from a beginning of the extent of the groove (4, 4') that is formed at an axial distance from the circumferential grooves (2, 3) axially with respect to a circumferential groove (2) over a first extent portion (5)and over a subsequent second extent portion (6) and opening into the circumferential groove (2), wherein the groove (4, 4') is formed with a width b which increases along the entire extent thereof between the beginning of the extent and the circumferential groove (2), wherein the groove (4, 4') in the course of the extent thereof between the first extent portion (5) and second extent portion (6) is formed with a buckling point (8), wherein the direction of extent of the groove (4, 4') from the beginning of the extent along the extent thereof in the first extent portion (5) as far as the buckling point (8) is formed with a greater direction component in the circumferential direction U than in the axial direction A, and between the buckling point (8) over the entire second extent portion (6)as far as the opening into the circumferential groove (2) is formed with a greater direction component in the axial direction A than in the circumferential direction, wherein the groove (4, 4') in the first extent portion (5) is formed with a depth T1 which increases continuously from the beginning of the extent along the extent over the first extent portion (5) until reaching the maximum value T1max thereof at the buckling point (8) and with a constant depth T2, where T2>=T1max, in the second extent portion (6).

Description

technical field [0001] The invention relates to a tread pattern of a pneumatic tire for vehicles, in particular a pneumatic tire for passenger cars, having at least one circumferential rib delimited outwardly in a radial direction R by a radially outer surface forming a contact surface , and is bounded in the axial direction A by a circumferential groove, wherein a transversely extending groove is formed in the circumferential rib, extending in the axial direction A from the beginning of the extent of the groove, along the circumference bounding the circumferential rib extending in the direction of the groove over a first extension and a second extension adjoining the first extension in the axial direction A, and entering the circumferential groove, the extent of which begins at a distance from these at an axial distance from the circumferential groove delimiting the circumferential rib, wherein the groove is formed with a width b measured in the radially outer surface and at ...
