ABSTRACT:
A pneumatic tire (10) has a tread (12) has a continuous center rib (24) extending circumferentially about the tread. A set of traction lugs (30,32) extend inwardly from each axial edge of the tread. Independent traction elements (58,60) are disposed circumferentially between circumferentially next adjacent traction lugs. The center rib (24) and the traction lugs (30,32) are substantially the same height, but the independent traction elements (58,60) have a lower height. An axially oriented arc of the tread has a radius such that a footprint of the tire has a maximum axial width that is in the range of 40% to 80% of the arc width of the tread.
