  • Patent number: 12187076
    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).

  • Patent number: 12109843
    Abstract: A rubber rib extending in the extension direction of a groove is respectively formed in profile element flanks which delimit the groove and each form a different groove wall. The rubber rib formed in one groove wall is formed in a different radial position than the rubber rib formed in the other groove wall. The two rubber ribs each extend over the entire extension length of the profile element flank and each of these two rubber ribs respectively extends along its entire extension length from that profile element flank in which it is formed into the groove in the direction of the other profile element flank up to at least the middle of the groove width in this radial position of the groove and ends there in the groove at a distance from the profile element flanks.

  • Publication number: 20240270024
    Abstract: A pneumatic tire for a vehicle with a tread having at least one profile rib, which is delimited on at least one side thereof by a circumferential groove. The circumferential groove has, when viewed in cross section, a portion running in the radial direction and having a width of up to 3.0 mm and, adjoining it, a radially inner channel region. The radially inner channel region is delimited by two channel walls and a channel base forming the groove base, and has a larger cross-sectional area and is made wider in each case than the portion running in the radial direction. The profile rib is provided over its circumference with sipes, which merge into the circumferential groove, run at an angle of 0° to 50° with respect to the axial direction and have a width of 0.4 mm to 1.2 mm and a maximum depth of 70% to 100% of the profile depth, and have sipe walls.

  • Patent number: 11766899
    Abstract: A pneumatic vehicle tire including a utility vehicle tire has a tread with profile positives which are separated from one another in a circumferential direction by transverse channels which extend continuously from the central region of the tread as far as the lateral tread edges, respectively. The transverse channels are main channels of the tread and, at least over the major part of the course thereof, have the maximum provided profile depth. The transverse channels are provided, on the respective channel base thereof, with a row of base elevations formed so as to be distributed over the entire course of the transverse channels. The base elevations are attached to the channel flanks of the transverse channels and are configured such that their rubber volume becomes smaller the closer to the tread edge they are disposed.
