A tire tread comprising: a tread width (T w) extending between a first lateral side edge and a second lateral side edge of the tire tread; a tread thickness (T t) extending from an outer, ground-engaging side of the tire tread to a bottom side of the tire tread, the tread thickness (T t) being perpendicular to the tread width (T w); a tread length (T l) extending perpendicular to both the tread width (T w) and the tread thickness (Tt); a groove having a depth (20 d) extending into the tread thickness (T t) from the outer, ground-engaging side of the tire tread and to a bottom thereof, the groove also having a length (20 l) and a width (20 w), the length (20 l) being dimensionally greater than the width (20 w), and the length (20 l), width (20 w), and depth (20 d) being perpendicular to each other, one or more split bridges arranged in the groove, each of the one or more split bridges having a length (24 l) extending in a direction of the groove length (20 l), a height (24 h) extending in a direction of the groove depth (20 d), and a width (24 w) extending substantially across the width (20 w) of the groove, each of the one or more split bridges having a discontinuity with a width equal to or less than 0.5 mm arranged along the width (24 w) of the corresponding split bridge and extending fully across the length (24 l) and height (24 h) of the corresponding split bridge, each of the one or more split bridges having a bottom side arranged closest to the bottom of the groove, the bottom side being spaced apart from the bottom of the groove to form a void between the corresponding split bridge and the groove bottom, each of the one or more split bridges having a top side arranged closest to the outer, ground-engaging side of the tread, where at least a portion of the top side is spaced apart from the outer, ground-engaging side in the depth (20 d) of the groove by a variable distance (Vi), where each of the one or more split bridges comprise a pair of projections (24A, 24B) extending from a pair of opposing sides (20 l, 20 2) of the groove defining the groove width (20 w), such that the discontinuity is arranged between a terminal end of each projection of the pair of projections (24A, 24B), characterized in that each of the one or more split bridges has a constant height (24 h) along its length (24 l) and the top side of each of the one or more split bridges extends along a non-linear path along the length (24 l) of the corresponding split bridge, where the top side for each projection extends along the non-linear path substantially and where the non-linear path is an alternating path, and where the top side of each projection is spaced apart from the outer, ground-engaging side of the tread by substantially the same distance as each top side extends along the non-linear path. a tread width (T w) extending between a first lateral side edge and a second lateral side edge of the tire tread;
