Tread of a tire (1) for a heavy-duty vehicle of civil engineering type. The tread (2), having an axial width WT and having a radial thickness HT at least equal to 70 mm, comprises at least two circumferential grooves (3) positioned axially on each side of an equatorial plane (XZ). Each circumferential groove (3) has an axial width W and a radial depth H, such that the ratio W/H is at least equal to 0.06, the axial distance C between two consecutive circumferential grooves (3) is at least equal to 12% and at most equal to 21% of the axial width WT of the tread and each of the axially outermost circumferential grooves (3) is positioned axially, with respect to the equatorial plane XZ, at an axial distance LE at least equal to 35% of the axial width WT of the tread.
