Beschreibung
Zusammenfassung:	The pneumatic tire tread has a radially outermost surface defining a circumferential length of the tire and the tread has at least one circumferentially extending groove. The groove has a spiral configuration across the tread surface and a pair of laterally spaced terminal ends. The circumferential length of the spiral groove, as measured between the terminal ends of the groove, is greater than 50% of the circumferential length of the tire. The spiral groove creates a spiral rib or projecting tread element row that moves across the tread width.
