Gravity Arc - Design for superb efficiency.

• Natural material shaping helps to spread the stressing more evenly.
• Roughened 3-D surfaces in the tread base improve the positive engagement between tire and terrain.
• The characteristic arches reinforce the lugs, so that they can get a better hold.
• The gripping edges of the tread work according to the Endless Edge principle. They counter the forces acting on thetread and ensure the tire stays in contact with the surface.
