Embodiment Construction

[0016] exist figure 1 shows a central tread region 2 bounded on both sides by a circumferential groove 1 in the tread of a pneumatic tire for vehicles in a radial structure and further tread bands or tread bands adjoining the central tread region 2 on both sides A row of blocks (only the axially inner region thereof is shown). The tread embodied according to the invention is preferably a tread for winter tires for passenger cars, vans or light trucks.

[0017] The shown central tread region 2 has two substantially identically embodied block rows 3, 3' which are separated from each other in the axial direction by circumferential grooves 4. As will be described more precisely, the circumferential groove 4 is interrupted by webs 5 over its circumferential extension.

[0018] Each block row 3, 3' is composed of tread block rows 6 successive to each other on the circumference of the vehicle pneumatic tire. A double tread block formed by grooves 7. as in figure 1 As shown ...

Abstract

The invention relates to a pneumatic vehicle tyre of radial type of construction, having a tread with at least two profile block rows (3, 3') which are delimited at the outside by in each case one circumferential channel (1) and which are separated from one another by a circumferential channel (4), wherein the profile block rows (3, 3') are divided into profile blocks (6) by transverse channels (8) which run substantially parallel to one another and which extend through the profile block rows (3, 3'), wherein the transverse channels (8) which run in one profile block row (3) run substantially parallel to the transverse channels (8) which run in the other profile block row (3'), and the profile block rows (3, 3') on the tread surface are delimited in each case by block edges (9, 10) running parallel to one another and have channel flanks (11, 12) running substantially in a radial direction, wherein in each case one transverse channel (8) from one profile block row (3) opens into the circumferential channel (4), which runs between the profile block rows (3, 3'), with an offset (a1) of 5.0 mm to 10.0 mm in the circumferential direction in relation to a transverse channel (8) from the other profile block row (3'). The circumferential channel (4) which runs between the profile block rows (3, 3') is, in each case between the transverse channels (8) which open into said circumferential channel (4) with an offset with respect one another, interrupted by a web (5) which connects a profile block (6) from one profile block row (3) to a profile block (6) from the other profile block row (3').

Description

technical field [0001] The invention relates to a pneumatic tire for vehicles in the form of a radial structure with a tread having at least two rows of blocks delimited on the outside by a circumferential sipe in each case and by a circumferential The grooves are separated from each other, wherein the block rows are divided into blocks by a plurality of transverse grooves running substantially parallel to each other and traversing the block rows, wherein in a block row The transverse grooves running substantially parallel to the transverse grooves running in another block row and the block rows are respectively block edges running parallel to each other at the tread surface Confining and having a plurality of sipe sides running substantially in the radial direction, wherein correspondingly the lugs from one row of blocks are present in the circumferential direction relative to the lugs from the other row of blocks Into the circumferential groove running between the rows of t...
