The new tire contour, combined with the patented tread design, significantly improves handling and reduces steering forces - providing maximum confidence in all driving situations. New design: The tread shape, inspired by the Greek letter "Pi," optimizes the flexibility of the tread and ensures an optimal contact patch under all conditions. With the 3-zone tension technology (InteractT-Technology), the "Z8" achieves outstanding mileage and perfect corner grip. A new composition of silica components with a nanometer-scale dispersion enhances performance and safety levels in all weather conditions.
