Tyre for a vehicle for agricultural use, comprising a tread intended to come into contact with the ground via a tread surface: - the tread comprising raised elements or lugs that are separated from one another at least in part by grooves and extend radially towards the outside from a bottom surface as far as the tread surface over a radial height H at least equal to 30 mm and at most equal to the radial thickness H max of the tread ; - the lugs being distributed in two circumferential rows (R1, R2); a first circumferential row (R1) being made up of a circumferential distribution of at least two families of lugs, distributed periodically around the circumference of the tyre; - the lugs of a first family being distributed circumferentially with a shortest spacing S, and the lugs of a second family being distributed circumferentially with a longest spacing L; each lug of the first circumferential row (R1) also being inclined at an angle Ψ with respect to the circumferential direction (XX') of the tyre; - the second circumferential row (R2) being obtained through symmetry of the first circumferential row (R1) with respect to an equatorial plane , passing through the centre of the tread and perpendicular to the axis of rotation (YY') of the tyre, followed by a rotational offset of angle θ about the axis of rotation (YY'); - the rotational offset being characterized by an overlap distance (R) between the lugs of the first circumferential row and those of the second circumferential row, defined as being the circumferential distance between the axially outer end of each lug of the first circumferential row (R1) and the axially inner end of the lug of the facing second circumferential row (R2), according to the direction of rotation of the tire , characterized in that the ratio S/L of the shortest spacing S of the first family of lugs to the longest spacing L of the second family of lugs lies within the range [0.6; 0.8], and in that the circumferential overlap distance R between the first and second circumferential rows of lugs is constant around the entire circumference of the tyre. - the tread comprising raised elements or lugs that are separated from one another at least in part by grooves and extend radially towards the outside from a bottom surface as far as the tread surface over a radial height H at least equal to 30 mm and at most equal to the radial thickness H max of the tread ; - the lugs being distributed in two circumferential rows (R1, R2); a first circumferential row (R1) being made up of a circumferential distribution of at least two families of lugs, distributed periodically around the circumference of the tyre; - the lugs of a first family being distributed circumferentially with a shortest spacing S, and the lugs of a second family being distributed circumferentially with a longest spacing L; each lug of the first circumferential row (R1) also being inclined at an angle Ψ with respect to the circumferential direction (XX') of the tyre; - the second circumferential row (R2) being obtained through symmetry of the first circumferential row (R1) with respect to an equatorial plane , passing through the centre of the tread and perpendicular to the axis of rotation (YY') of the tyre, followed by a rotational offset of angle θ about the axis of rotation (YY'); - the rotational offset being characterized by an overlap distance (R) between the lugs of the first circumferential row and those of the second circumferential row, defined as being the circumferential distance between the axially outer end of each lug of the first circumferential row (R1) and the axially inner end of the lug of the facing second circumferential row (R2), according to the direction of rotation of the tire , <EOS>
