Excellent safety on wet roads. In deep water... a directional tread pattern with wide circumferential grooves maximises water dispersal to reduce the risk of aquaplaning. or on normal wet roads, the g-Grip features a "vortex" tread pattern, designed to disperse water more quickly for better braking and handling. Unrivalled driving pleasure on dry roads. On straights and in bends... substantial shoulder tread blocks and a continuous central rib give a rapid steering response and superb control. ...with improved braking, its "chamfered edge" sipes improve the stability of each tread block for better braking on dry roads.
