摘要： A radial tire for drive wheels of agricultural tractors has two staggered rows of raised lugs each occupying one half of the tread. Each lug consists of an axially outward segment forming an angle of from 85.degree. to 100.degree. with the circumferential direction of the tire and an axially inward segment connected to the axially outward segment by an intermediate segment and forming an angle less than 30.degree. with the circumferential direction of the tire and about equal to the angles of the tread reinforcement plies, the latter being arranged between the tread and the radial carcass reinforcement. The quasi-cylindrical tread reinforcement has an axial width at most equal to 0.9 times the axial width of the tire and the radial carcass reinforcement reaches its maximum meridian curvature in the region of the shoulders.
