The present invention relates to a tread (2) for an agricultural-vehicle tyre, the traction performance of which on loose ground is improved. The tread (2) comprises main tread-pattern elements (21) having a radial height HR1 and secondary tread-pattern elements (31), disposed longitudinally between the main tread-pattern elements (21), having a radial height HR2 and comprises a leading face (312) inclined at an angle α toward the front with respect to the radial direction (Z) in the rolling direction (15) and a contact face (311) inclined at an angle β toward the rear with respect to the radial direction (Z) in the rolling direction (15). According to the invention, the ratio HR1/HR2 is at least equal to 4, the angle α is between -5 degrees and 15 degrees, the angle β is between 95 degrees and 110 degrees, and the longitudinal spacing L separating the secondary tread-pattern elements (31) from one another is between 5 mm and 50 mm.
