Pneumatic vehicle tyre

A pneumatic vehicle tire comprising a tread with profile blocks formed by circumferential or diagonal grooves and by transverse grooves, wherein the profile blocks each have at least one sipe which is straight or slightly curved and extends at least substantially parallel to the transverse grooves, wherein the at least one sipe has a width of 0.3 mm to 2.0 mm, wherein the sipe is bounded by two sipe walls, and wherein at least one protrusion is provided on each of the two sipe walls;

• wherein the protrusion formed on one of the two sipe walls is offset with respect to the protrusion formed on the other of the two sipe walls, without a mutual overlap;
• wherein each protrusion provided on each of the two sipe walls has a rounded outer face, and wherein tangents (Ta) through points at the longitudinal ends of each of the protrusions enclose an angle α of 10° to 30° with the sipe wall;
• wherein the protrusions extend at an angle (β) of up to 20°, relative the radial direction, provided the angle (β) is not 0°;
• and,
• wherein each round face of each of the protrusions is curved in the radial direction.
