A tire includes a plurality of tire knobs of various shapes arranged to form contact surfaces configured to touch the ground. The contact surface is the radially outermost surface of each knob which may be formed in a variety of three-dimensional structures such as pyramids, wedges, cones, and others. The contact surfaces may be points, lines or a combination of both. The contact surface lines may be segmented as a result of gaps between adjacent knobs that are aligned with each other. The contact surfaces may also be line segments joined to each other at offset angles to form a zig-zag pattern. Each contact surface may be centered or off-centered with respect to the base of the knob. |
