Abstract
A tread for a heavy vehicle tire, comprising at least one tread design component () delimited by at least two grooves, each component comprising a contact face () limited by edges (); the contact face () having, viewed in a cross-sectional plane substantially perpendicular to the contact face of the tread and cutting two of the edges of the motif at Aand A, a plot whose geometrical profile P between the points Aand Ahas at least one bump () in relief relative to a virtual straight line D passing through the points Aand A, the point B, Bof each bump () that is furthest from the straight line D being located a height Hi from this straight line and a distance Di from the point Aor Athat is the closer, with 0.1<Di/L<0.25, where L is the distance separating the points Aand A, and 0.1 mm<Hi<2.5 mm. In addition, the profile P passes through a point C located a distance Hc (0 mm<Hc<Hi/2) from the straight line passing through Aand Aand substantially halfway between the points Aand A
