Title: PNEUMATIC VEHICLE TYRE
Abstract:
Pneumatic vehicle tyre with a profiled tread (1), which consists of electrically nonconductive rubber material and has a central tread region (3) and on each of the shoulder sides a row of profile blocks (2) with transverse grooves (7), which extend in relation to the circumferential direction at an angle (β) of 70° to 90°, wherein the shoulder-side profile blocks (8) have towards the centre of the tread block ends (8’), wherein the central tread region (3) is divided into a multiplicity of profile blocks (4) and is provided with grooves (5), which extend in relation to the circumferential direction at angles (a) of at most 60°, wherein all of the profile blocks (4, 8) are each provided with a number of sipes (9, 9’), and wherein the tread (1) is passed through in the radial direction by at least one circumferentially running electrically conductive rubber strip (14), which forms an electrically conductive passage between the substructure of the tyre and the outer surface of the tread. The tread (1) is passed through in at least one of the shoulder-side rows of profile blocks (2) by an electrically conductive rubber strip (14), which is at a distance (al) of at least 3.0 mm from the nearest block corners (8’) of the shoulder-side profile blocks (8) or block-like profile positives.
