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.

Pneumatic tyre for a vehicle

A pneumatic vehicle tire, in particular utility vehicle tire, having a tread which has a directional profiling with shoulder-side and middle profile ribs running in a circumferential direction, wherein at least one of the middle profile ribs (), which is in particular a profile rib running along the tire equator, is traversed in an axial direction by sipes () with a width (b) of 0.5 mm to 1.2 mm, each of which has a central portion (), in which the sipe () runs with an undulation in the direction of extent thereof, and two lateral portions (). The sipes () extend, in plan view, in an arc shape and symmetrically with respect to the centerline of the profile rib (), and, in the lateral portions () and in the central portion (), have a uniform undulation running in the radial direction, on which the undulation present in the extent direction of the sipes () is superposed only in the central portion () of the sipe ().
