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. Each sipe is locally widened by at least one channel which is open to the tread periphery and merges into the radially inner channel region of the circumferential groove. The channel is formed by a depression formed in one sipe wall and a depression formed on the other sipe wall, opposite the first depression.

Pneumatic tire 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 ().
