A directional, symmetrical tread (12) for a tire (10) is disclosed. The tread (12) has a row (40) of elements (30, 32) which have leading and trailing edge surfaces relative to the direction of forward travel. Between the leading edge (70) of the second element and the trailing edge (74) of the first element is a tie bar (66) having a radial height which varies across the lateral width of the tie bar (66) and circumferential length of the tie bar (66).
