++New profile design with more tread volume (greater land/sea ratio) in the shoulders for excellent cornering grip and a more open center-tread area for straight-line grip. ++Recessed biting edges in shoulder tread blocks yield more traction for greater grip, especially in corners and ruts, throughout a wide range of terrain conditions. ++Chiseled shoulder block shape improves side traction and makes traversing ruts easier. This tapered shape facilitates knob penetration through soft surfaces, whereas a flat knob would �float� and/or be deflected. Instead, the tapered knob penetrates into the firmer underlying ground to give the tire more bite for more traction. ++Tie-bar design connects and reinforces the tread blocks for greater tread stiffness, yielding improved intermediate-to-hard terrain performance. ++Recess design in the area between tread blocks gives the tire improved compliance for enhanced ride comfort. Enhanced land/sea ratio and wider tread profile for improved traction. ++Larger-radius tread block base for strength and increased durability.
