Abstract:
A vehicle wheel tire includes a tire tread having a circumferential center tread region in which block elements are arranged in a symmetric pattern on opposite sides of a tire circumferential equatorial centerplane. The tread has one or more circumferential grooves bounded by edges of opposing block elements, pairs of opposed block elements having a block edge facing the groove and an array of saw-teeth formed along the groove-facing edge of opposed block elements inclined in the radial direction. The saw-teeth on a block edge of one opposed block element incline in a direction opposite to the inclination direction of saw-teeth on opposite opposed block element. A block element on the center tread region side of the groove has multiple circumferentially spaced apart and laterally extending sipes extending across the block element. The sipes extend to and align with the array of saw-teeth along the groove-facing edge of the block element.
