Tire

A tire has a circumferential tread, the tread including shoulder tread regions configured for off-road performance separated by and interlocking with a center tread region configured for on-road performance. The shoulder tread regions are defined by a repeating pattern of two or more distinct shoulder tread elements and the center tread region is defined by a repeating pattern of two or more distinct center tread elements. The shoulder tread elements each have a ground contacting surface area greater than a ground contacting surface area of the center tread elements. The center tread elements extend at a relatively greater angle of inclination with respect to an equatorial centerplane of the tire and the shoulder tread elements extend at a relatively lesser angle of inclination with respect to the centerplane. The center tread elements and the shoulder tread elements are irregular and asymmetrical about a longitudinal central axis and a transverse central axis and, together, total five or more (three in the center tread region and two in the shoulder tread region) tread blocks of mutually distinctive geometric shape.

Tire tread

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.
