Pneumatic tyre for a vehicle

Vehicle pneumatic tire with a patterned tread comprising profile structures that include profile positives, such as profile blocks (1a, 2a) arranged in profile block rows (1,2), and profile negatives, such as circumferential grooves (3,4) and transverse grooves (6,7), wherein the profile positives are arranged noise-optimized over the tire circumference according to at least one specified pitch sequence and according to a method of pitch length variation. Ribs (9, 9', 9") are locally arranged on profile positives, which ribs extend at an angle to the axial direction of the tread and are arranged noise-optimized over the tire circumference according to a sequence that differs from the pitch sequence of the profile positives on which the ribs (9, 9', 9") are positioned.
