Increased 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 grooves
Rebalanced tire stiffness to allow a better adherence of the rubber with the tarmac micro-asperities, increasing mechanical grip even on lower friction surfaces
Belt and carcass tension parameters upgraded to increase stability on rear tires during strong braking
Increased mileage vs. Roadtec Z8 Interact (up to 10%), thanks to a different footprint shape (larger and shorter) which also enhances motorcycle handling
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 life
Metzeler multi-zone compound on selected sizes, with increased harmonization between the different compounds
I installed the Roadtec 01 HWM tires on my 2008 BMW R1200RT replacing Michelin PR4's that I really liked.I rode cross country putting over 6200 miles on the roadtecs in all weather,heat and driving rain.Most of the riding was on interstates,so center wear was my biggest concern.After coming home and looking at the tires,I would guess there is still 3000 of wear on them..I am very impressed,better dry handling than the michelins and comparable wet handling.They might exhibit a little more road noise although.I'd buy another pair and recommend them.
