Abstract
Tire () for an agricultural vehicle, and more particularly the tread () thereof, has improved traction in the field, while reducing the sensitivity of the lugs () to attack by stubble. Each lug () comprises first lug portion (), having height H1, and second lug portion (), having height H2 and having a mean angle of inclination A2 with respect to circumferential direction (XX') of the tire. The first lug portion () is comprised of a radial superposition of N layers C1(), where i varies from 1 to N, each having a height H1, each layer C1having a mean angle of inclination A1strictly less than the mean angle of inclination A2, and, when N is strictly greater than 1, the angle A1relative to a layer C1, where j varies from 1 to N−1, is strictly less than the angle A1relative to the layer C1.
