ABSTRACT:
An add-on track system for an all-terrain vehicle is disclosed. ATV tires are very soft and flexible, and apt to climb out of a track if the track is not properly located. The invention has a track segment with arms protruding up from the slope-plate of the segment, and the arms converge inwards. The upper ends of the arms locate the segment against the tire side walls, but at a level on the sidewalls where the tire profile is free of the bulging under load which is so marked in ATV tires. The segments have holes through the sole-plate, through which the overhanging parts of the converging arms can be moulded, without movable cores. Retractable cleats occupy these holes, and are forced out when the tire bulges under load.
