Abstract: Tire (1) for an agricultural vehicle, and more particularly the tread (2) thereof, has improved traction in the field, while reducing the sensitivity of the lugs (3) to attack by stubble. Each lug (3) comprises first lug portion (31), having height H1, and second lug portion (32), having height H2 and having a mean angle of inclination A2 with respect to circumferential direction (XX?) of the tire. The first lug portion (31) is comprised of a radial superposition of N layers C1i (33), where i varies from 1 to N, each having a height H1i, each layer C1i having a mean angle of inclination A1i strictly less than the mean angle of inclination A2, and, when N is strictly greater than 1, the angle A1j relative to a layer C1j, where j varies from 1 to N?1, is strictly less than the angle A1j+1 relative to the layer C1j+1.

Abstract: Tire (1) for an agricultural vehicle and more particularly to the tread (2) thereof. The tread has a radial thickness Hmax and comprises a middle part (20) and two lateral parts (21, 22), the meridian profile (PS) of the radially outer surface (31, 32) of each lateral part (21, 22) is radially on the inside of the meridian profile (PC) of the radially outer surface (30) of the middle part (20) and the radial distance (d) between the midpoint (I1, I2) of the meridian profile (PS) of the radially outer surface (31, 32) of each lateral part (21, 22) and the meridian profile (PC) of the radially outer surface (30) of the middle part (20) is at least equal to 0.5 times the radial thickness Hmax of the tread (2).
