Patent attributes
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.
