Tyre for an agricultural vehicle, having a nominal section width L, within the meaning of the ETRTO standard, and comprising, radially from the outside to the inside, a tread and a crown reinforcement , - the tread comprising tread pattern elements that are separated from one another by voids and extend radially towards the outside from a bearing surface to a tread surface , - the tread having a volumetric void ratio TEV, defined as the ratio between the volume of voids VC and the total volume of the tread assumed to be free of voids V, comprised between the bearing surface and the tread surface , - each tread pattern element having a circumferential slenderness H/B, H being the mean radial height between the bearing surface and the tread surface and B being the mean circumferential length of the tread pattern element , - each tread portion , positioned axially, with respect to an equatorial plane (E) of the tyre, at an axial distance DE, having an axial width LE and a local volumetric void ratio TEVL, defined as being the ratio between the volume VCL of the voids and the total volume VL of said tread portion , comprised between the bearing surface and the tread surface , - the crown reinforcement comprising at least two crown layers , each comprising metal reinforcers that are coated in an elastomeric material, are mutually parallel and form an angle at least equal to 10° with a circumferential direction (XX'), characterized in that, for each tread portion , positioned axially, with respect to the equatorial plane (E) of the tyre, at an axial distance DE at most equal to 0.36*L, and having an axial width LE equal to 0.08*L, the product TEVL*(H/B) of the local volumetric void ratio of the tread portion and the circumferential slenderness H/B of each tread pattern element of said tread portion is at most equal to 0.35 and in that the tread comprises a total number N of tread pattern elements , each tread pattern element comprising a contact face , a leading face and a trailing face , said leading face being inclined by an angle A towards the rear with respect to the radial direction (ZZ') in the direction of running (R) of the tread , said tread comprising a number N1 of tread pattern elements for which the angle α is comprised between 50 degrees and 75 degrees, the number N1 being at least equal to 0.2xN. - the tread comprising tread pattern elements that are separated from one another by voids and extend radially towards the outside from a bearing surface to a tread surface , - the tread having a volumetric void ratio TEV, defined as the ratio between the volume of voids VC and the total volume of the tread assumed to be free of voids V, comprised between the bearing surface and the tread surface , - each tread pattern element having a circumferential slenderness H/B, H being the mean radial height between the bearing surface and the tread surface and B being the mean circumferential length of the tread pattern element , - each tread portion , positioned axially, with respect to an equatorial plane (E) of the tyre, at an axial distance DE, having an axial width LE and a local volumetric void ratio TEVL, defined as being the ratio between the volume VCL of the voids and the total volume VL of said tread portion , comprised between the bearing surface and the tread surface , - the crown reinforcement comprising at least two crown layers , each comprising metal reinforcers that are coated in an elastomeric material, are mutually parallel and form an angle at least equal to 10° with a circumferential direction (XX'), <EOS>
