A tread (10) for a tire (1) having a plurality of tread components (20) comprising a sipe (100) defining first (101) and a second (102) opposing faces; the said sipe (100) having a sipe depth (P) and comprises in sequence, from a radially external position to a radially internal position, a first (A) and a second (C) section, wherein an intermediate section (B) links said first (A) and second (C) section and wherein said first (101) and second (102) opposing faces define first profiles (101 a, 102a) along said first section (A) with a plane (γ) orthogonal to a longitudinal extension direction (L) of said sipe (100), said first profiles (101a, 102a) presenting a pattern such as to intersect a straight line lying in said orthogonal plane (γ) in at least two distinct points, and define second profiles (101 c, 102c) along said second section (C) with said orthogonal plane (γ), said second profiles (101c, 102c) presenting a substantially rectilinear pattern; said first (101) and second (102) opposing faces- are continuously and increasingly spaced apart between a minimum depth (Pmin) and a maximum depth (Pmax ) in the intermediate section (B).
