Abstract: A tire having a tread with profile rib traversed by sipes, which extend parallel to one another and at an angle of 0° to 50° relative to the axial direction and have a width of 0.4 mm to 3.0 mm. Each sipe has a sipe main portion extending over the majority of its extent and via a respective sipe edge portion leads into each circumferential groove delimiting the profile rib. The sipe main portion and the sipe edge portion have a respective depth in which the depth of the sipe main portion is less than the depth of the sipe edge portion. In the interior of the profile rib, the sipe edge portion over its entire extent leads into a cavity that extends from the circumferential groove and is made wider than the sipe.

Abstract: The invention relates to a pneumatic vehicle tire, in particular utility vehicle tire, having a tread with at least one profile rib (1) which runs around in the circumferential direction, is delimited on at least one side by a circumferential groove (2a) formed to a profile depth (T1), and is traversed by sipes (3), which extend parallel to one another and at an angle of 0° to 50° in relation to the axial direction at least in groups in plan view and have a width (bE) of 0.4 mm to 3.0 mm, wherein each sipe (3) has a sipe main portion (3b) extending over the majority of its extent and by way of a respective sipe edge portion (3a) leads into each circumferential groove (2a) delimiting the profile rib (1), wherein the sipe main portion (3b) and the sipe edge portion (3a) have a respective depth (ta, tb) in a radial direction and the depth (ta) of the sipe main portion (3b) differs from the depth (tb) of the sipe edge portion (3a).

Abstract: A pneumatic vehicle tire for utility vehicles includes a carcass, a profiled tread and a belt formed from at least four belt plies arranged lying one on top of the other. The belt plies are formed with parallel strength members embedded in rubber. The second belt ply and the third belt ply are working plies. The strength members of the second belt ply have an opposite axial direction of inclination in relation to those of the third belt ply. The strength members of the first belt ply and the strength members of the third belt ply and the strength members of the fourth belt ply are oriented in the tire with the same axial direction of inclination.
