Abstract
A vehicle tire tread includes a circumferential spaced apart array of discrete tie-bar block elements within a circumferential tread groove, each tie-bar block element having a circumferentially oriented bisecting cut dividing the tie bar into opposed tie-bar components. The opposed tie-bar components operatively flex and converge axially when present within a rolling tire footprint to close the radially outward cut segment and resume a nominal separation dimension when outside a rolling tire footprint. The bisecting cut within each tie-bar block element further forms at a radially inward end a large diameter fluid conducting channel extending through the tie-bar block element to allow the passage of fluid along the circumferential groove, unobstructed by the array of tie-bar block elements.
