摘要： A vehicle wheel tire having a symmetrical five rib tread construction with adjacent tread ribs comprising the tread separated by circumferential grooves. The intermediate tread grooves have an axial width wider than an axial width of the shoulder grooves and a center rib has an axial width wider than the axial widths of the intermediate ribs and the shoulder ribs. The axial width of the center rib, intermediate ribs, and shoulder ribs are within a prescribed preferred range of a total tread axial width and the axial width of each intermediate groove is within a prescribed preferred range of total tread axial width.

摘要： 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.
