Higher wear resistance, obtained through a revised land/sea ratio on the rear tire in conjunction with the new tread design, ensures product performance consistency allowing users to enjoy the tire for its entire service lifeIncreased grip on wet roads, with a focus on low friction surfaces (such as city streets and worn tarmac, low temperature), thanks to radial positioning of groovesRebalanced tire stiffness to allow a better adherence of the rubber with the tarmac micro-asperities, increasing mechanical grip even on lower friction surfacesIncreased mileage vs. Roadtec Z8 Interact (up to 10%), thanks to a different footprint shape (larger and shorter) which also enhances motorcycle handlingHWM (Heavy Weight Motorcycles) special version to improve performance (see Metzeler website for details) ASPECT RATIO55Aspect Ratio55CONSTRUCTIONR (Radial)ConstructionR (Radial)LOAD/SPEED INDEX(73 W)Load/Speed-Index(73W)MARKET SEGMENTCruiser / StreetMarket SegmentCruiser / StreetMounting PositionRearPOSITIONRearPRODUCT NAMETirePositionRearProduct NameTireRIM DIAMETER17Rim Diameter17SECTION WIDTH180SIDEWALLBlackwallSPECIFICATIONHWMSTYLESport Touring| Street RadialSidewallBlackwallSpecificationHWMStyleHeavy-Touring, Sport Touring, StreetTIRE SIZE180/55R17TREAD PATTERN/MODELRoadtec 01TUBE TYPETubelessTire Size180/55ZR17Tread Pattern/ModelRoadtec™ 01Tube TypeTubelessUNITSEachUnitsEachVendor part number2681300Width180
