Open inner zone covered with arc-like voids to completely evacuate water and protect tire from hydroplaning. Outer zone comprised of large smooth tread blocks helps provide better handling and stability at high speed and in extreme situations. Closed outer shoulder zone reduces noise level during the tire-road contact.Circular ribs in the tread center provide enhanced road-holding ability, precise steering response and high breaking properties on wet and dry roads. Broad central circular and cross-sectional grooves offer better rolling dynamics and enhanced gripping traction on wet road surface. Half open sipes in middle ribs offer additional road adhesion and reduce breaking distance.
