Certain elements in relief (11, 13) of a tread (1) for a radial tire are provided at least with incisions (41, 42, 43) which in cross-section have a fork-shaped outline with at least two branches (41B, 41C) forming an extension of a single part (41A), the number of incisions (41) in the element in relief (11, 13) being multiplied by a factor equal to at least 1.5 starting from the depth (h1) of the double-branched incision (41). Use of such treads for tires intended to travel on wet, snow-covered or icy ground.
