A Tire tread with blocks for a heavy construction-plant vehicle, to improve the compromise between traction on muddy ground and lifetime in terms of wear on rough ground. A tread (1) has blocks (4), which are separated by cuts (3) and raised with respect to a bottom surface (5). Any block (4) have a contact face (41) having a polygonal shape of surface area SC, which is contained in a tread surface (2), lateral faces (42), and a base section (43), which has a polygonal shape of surface area SB. The contact face (41) of any block (4) has a polygonal shape that is at least partially concave, wat least two consecutive sides (411, 412) that form between them an interior angle A1 of the polygonal shape that is greater than 180° and the surface area SC of the contact face (41) is at most equal to 0.9 times the surface area SB of the base section (43).
