<p>A tread for a heavy vehicle tire, comprising at least one tread design component ( 3 ) delimited by at least two grooves, each component comprising a contact face ( 4 ) limited by edges ( 7, 8 ); the contact face ( 4 ) 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 A 1 and A 2 , a plot whose geometrical profile P between the points A 1 and A 2 has at least one bump ( 9, 10 ) in relief relative to a virtual straight line D passing through the points A 1 and A 2 , the point B 1 , B 2 of each bump ( 9, 10 ) that is furthest from the straight line D being located a height Hi from this straight line and a distance Di from the point A 1 or A 2 that is the closer, with 0.1<Di/L<0.25, where L is the distance separating the points A 1 and A 2 , 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 A 1 and A 2 and substantially halfway between the points A 1 and A 2.</p> |
