Tread of a tire for an agricultural vehicle. The tread (2) comprises a first, median portion (21) having an axial width L1, at least equal to 0.25 times and at most equal to 0.75 times the axial width L, and second and third, lateral portions (22, 23) that respectively extend axially outwards from the first, median portion (21) as far as an axial end (E, E′) and have respective axial widths (L2, L3). Each lug portion (311) that is axially contained in the first, median portion (21) and extends radially inwards, from the contact face (6) as far as a first interface (7), over a radial distance D1 at least equal to 0.5 times and at most equal to 1 time the radial lug height H, includes a first elastomeric compound. Each lug portion (321) that is axially contained in one of the second or third, lateral portions (22, 23) and extends radially inwards, from the contact face (6) as far as a second interface (8), over a radial distance D2 at least equal to 0.5 times and at most equal to 1 time the radial lug height H, includes a second elastomeric compound.
