Patent ID: 11148475

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.
