The mark consists of a three-dimensional configuration of a tire tread, comprised of a series of repeated designs with each row consisting four irregular polygons in an offset pattern. There is a void space separating each polygon. The first row consists of: the first polygon on the left is nine-sided, with a jagged edge on the top right; the second polygon from the left and the third polygon from the left are each is eight-sided, facing opposite directions, with polygon containing a zig-zag break in the middle, and with a stepped- or jagged edge on the lower left edge and upper right edge, respectively; the right-most polygon is nine-sided, with a jagged edge on the top left. The second row consists of: the first polygon on the left is nine-sided, with a jagged edge on the bottom right; the second polygon from the left and the third polygon from the left are each is eight-sided, facing opposite directions, with polygon containing a zig-zag break in the middle, and with a stepped- or jagged edge on the lower left edge and upper right edge, respectively; the right-most polygon is nine-sided, with a jagged edge on the bottom left. The third and fourth rows repeat the first and second rows of irregular polygons. The matter depicted in broken lines is not claimed as a feature of the mark and serves only to show the position or placement of the mark.
