A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

A track assembly for a terrain going vehicles having tires, the track assembly having at least two traction bars. The traction bars each having a body that is dimensioned to extend over the width of a tire and guide plates extending from the body so that they can be set to reach over the edge of the tire and to the sides of the tires and ears at each end of each traction bar, extending crosswise on relation to the length of the traction bar and on both sides of the body of the traction bar, the ears having each at least one hole. There is at least one link having a link body with a length and one connecting hole at each opposite end of the link body, and pins set to run through a pair of one hole of the link body and at least one hole of a ear of the traction bar in order to form a chain, wherein the pins are locked in relation to the holes of the ears so that rotation of the pins in the holes is prevented.

An anti-skid device includes a first main body and a second main body disposed rearward of the first main body, both of which are made of elastic material. The first main body has: a first ground-contactable sheet-like part that elongates in a circumferential direction; an inside rear connecting part provided at rear side of the first ground-contactable sheet-like; and an outside front connecting part provided at front side of the first ground-contactable sheet-like part. The second main body has: a second ground-contactable sheet-like part that elongates in the circumferential direction; an inside front connecting part provided at front side of the second ground-contactable sheet-like part; and an outside rear connecting part provided at rear side of the second ground-contactable sheet-like part. The inside rear connecting part of the first main body and the inside front connecting part of the second main body are connectable with each other.
