Abstract
PURPOSE:To ensure excellent travelling property on uneven ground, by solidifying a road surface by pressurizing and compressing gravel, etc. among a first projection and second projections by moving the second projections at both sides of the first projection to the first projection when the first projection contacts with the earth. CONSTITUTION:This tire 15 for uneven ground is provided with a tread pattern shown in the development drawing, and produced by mounting a rectangular block-like projection 10 onto a central line N-N of the tire in a projecting shape. Four projections 11 - 14 are mounted onto two diagonal lines (a), (b), which intersection point is the central projection 10, at the outside of the projection 10. Each projection 11 - 14 is shaped in five-cornered forms, and a comparatively large space portion S is shaped at the inside of a quadrilateral (c) formed by joining the outside vertexes. Consequently, when the central projection 10 contacts the earth and is indented in the inner diameter direction of the tire 15, each projection 11 - 14 moves in the central projection 10 direction, holds gravel, etc. in the space portion S and can increase the driving force of the tire.
