Everything about the New Roadtec Z8 Interact has been designed to put the rider in control. It responds like an extension of the rider's instincts, creating an invigorating blend of precise riding feel and effortless handling. New high silica compound with nano-particles increases performance and safety in all weather conditions. All-New profile matched with New patented tread design provides easy handling and reduced push steering for maximum confidencein all maneuvers. A final footprint area 8% wider as compared to its predecessor due to the variation of steel belt tensions and a strategically placed tread patternwhich optimizes pressures in the footprint area. The Roadtec Z8 Interact achieves its best-in-segment mileage and optimal wet performance throughout the tire's life thanks to an innovative treadpattern, a widened and more elliptical footprint, and a host of wear-resistant technologies not normally seen in motorcycle tires. Metzeler's New patented tread pattern reduces front tire land-sea ratio to 11% and the rear tire land-sea ratio of 13%. Strategically placed longitudinal central grooves provide ideal drainage for more than 3/4 of all lean angles in the wet. The remaining tread grooves work to add treadflexibility, extending the footprint for stability in the dry. The updated design of the Roadtec Z8 improves wear regularity which gives riders the benefit of a consistent riding performanceacross the tire's entire life. Tubeless (TL).
