The invention relates to a tread of a tyre for a farm vehicle, in which the tread is efficient in terms of wear and resistant to attacks. Such a tyre (1) includes a tread (2), including lugs (3) separated by grooves (4), each lug (3) extending radially outwards, over a radial height H, from a bottom surface (5) to a contact surface (6). A first lug portion (31), made of a first elastomer mixture, extends radially inwards, from the contact surface (6) to a first interface (7), over a radial distance D1 equal to at least 0.5 times and no more than once the radial height H. A second lug portion (32), made of a second elastomer mixture, extends radially inwards, from the first interface (7) to the bottom surface (5), over a radial distance D2. The second elastomer mixture extends radially inside the lugs (3) and the grooves (4), from the bottom surface (5) to a second interface (8), over a radial distance D3 equal to at least 3 mm and no greater than 15 mm. |
