Tire

A pneumatic tire comprises an annular tread portion including a plurality of circumferentially extending main grooves comprising an innermost groove, an outermost groove, and at least one middle groove arranged between the innermost groove and the outermost groove. The outermost groove comprises an inner sidewall, an outer sidewall, a groove bottom, and a groove opening opposite to the groove bottom, wherein the outermost groove has an asymmetric cross section with respect to any straight line perpendicular to the groove opening, and wherein the outer sidewall of the outermost groove is tilted by more than 20&#xb0; with respect to a straight line perpendicular to the groove opening.

Tire comprising a tread with asymmetric groove profiles

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.
