Abstract: 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 (1), which is in particular a profile rib running along the tire equator, is traversed in an axial direction by sipes (4) with a width (b1) of 0.5 mm to 1.2 mm, each of which has a central portion (4a), in which the sipe (4) runs with an undulation in the direction of extent thereof, and two lateral portions (4b). The sipes (4) extend, in plan view, in an arc shape and symmetrically with respect to the centerline of the profile rib (1), and, in the lateral portions (4b) and in the central portion (4a), have a uniform undulation running in the radial direction, on which the undulation present in the extent direction of the sipes (4) is superposed only in the central portion (4a) of the sipe (4).

Abstract: A method is for determining a profile depth of a tire profile. The method includes at least the following steps: a) detecting an acceleration of a measurement point on a tire inner side of a vehicle tire, wherein a deviation, caused by contact of the vehicle tire with a roadway, of the acceleration of the measurement point within an observation window is detected, b) deriving at least one analytical characteristic variable which is characteristic of the profile of the detected acceleration, wherein the at least one analytical characteristic variable characterizes the non-periodic profile of the detected acceleration within one tire rotation, c) determining the profile depth in a manner dependent on the at least one analytical characteristic variable, wherein a calibration curve yields the dependency between the analytical characteristic variable and the profile depth, and the calibration curve assigns a profile depth to the derived analytical characteristic variable.
