A track belt assembly includes an elastomeric track member which forms a closed loop. The elastomeric track member is advanced in a path of movement when a work machine is advanced in the forward direction of movement. The track belt assembly further includes a number of elastomeric tread bars mounted on an outer surface of the track member. A first cross section of each of the number of tread bars which is taken in a longitudinal direction which is oriented parallel to the forward direction of movement defines a leading terminal end point, a leading edge transition point, a trailing edge transition point, and a trailing terminal end point. The distance between the track member and each point of the first cross section which is interposed between the leading terminal end point and the leading edge transition point is smaller than the distance between the track member and the leading edge transition point. The distance between the track member and each point of the first cross section which is interposed between the trailing terminal end point and the trailing edge transition point is smaller than the distance between the track member and the trailing edge transition point. A leading longitudinal distance is defined between the leading terminal end point and the leading edge transition point. A trailing longitudinal distance is defined between the trailing terminal end point and the trailing edge transition point. The trailing longitudinal distance is greater than twice the leading longitudinal distance.
