Abstract: A tread is configured to have three rows of tread elements, a center row and a pair of shoulder rows, the center row forming a circumferential rib positioned at an equatorial centerplane of the tread. Each shoulder row has a repeating circumferential array of upwardly extending elongate groove fingers, adjacent groove fingers within the repeating array of each shoulder row of groove fingers being connected by at least one laterally extending channel. An array of serrations line each longitudinal side of the channels, each serration defined by inward tapering serration sidewalls extending to a serration base surface. Each channel is submerged below an outward tread surface such that the submerged channel will emerge as the tread wears down.

Abstract: Vehicle tire having a tread rubber profile which includes grooves running in a circumferential direction, diagonal grooves, two shoulder block rows and a pair of center block rows arranged between the two shoulder block rows. Each of the two shoulder block rows and each of the pair of center block rows include blocks. Each of the blocks include a plurality of fine indents running generally parallel to one another. The tread rubber profile has a road contact area defined by a width Y and a center profile area defined by a width X, whereby the width Y at least partially encompasses the two shoulder block rows and whereby the width X is generally defined by axial outer edges of the pair of center block rows. A ratio of the width Y to the width X is between approximately 1null(DRnull100)null1.5 and approximately 1null(DRnull100)null5, whereby DR represents a diameter of a rim to which the vehicle tire can be connected. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
