Tread (10) for a tire of an off-road vehicle. Total width Wt of the tread is greater than 600 mm and has at least three circumferential main grooves (1, 2, 3, 4) at least 60 mm deep that divide the tread into intermediate ribs (51, 52, 53) and edge ribs (8). The edge ribs have a width≤0.25 Wt. At least one of the intermediate ribs (51, 52, 53) has fine grooves (61, 62, 63) of depth H1 delimiting blades of material (71, 72, 73) of mean width B1<2H1. Grooves (61, 62, 63) are oriented in the axial direction of the tire. Each intermediate rib (51, 52, 53) has a mean width≤0.25 Wt and ≥0.75 Ht (thickness of material to be worn away). Grooves, (61, 62, 63) have, over a height H12 at least equal to 65% of H1, a width≤ to the value obtained from 0.04√{square root over (B1·H1)}.
