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. Symmetrically disposed block elements on opposite sides of the centerplane have a plurality of spaced apart and laterally extending wavy sipes extending across the block element. Selective pairs of adjacent sipes are interconnected by one or more circumferentially oriented notches. The wavy sipes have regions of varying depth and include one or more recessed region(s) and one or more non-recessed region(s). A circumferentially disposed notch interconnecting a pair of adjacent wavy sipes at opposite notch ends intersects the wavy sipes at non-recessed sipe regions.
