    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.

    摘要： A tire for a motor vehicle having a radial carcass and a top belt construction which includes a filler section in the lower portion or flange portion of each sidewall. The filler section is positioned between a portion of the carcass and folded over edges of the carcass and is comprised of a rubber material having a dynamic modulus at least about 200 kg/cm.sup.2 and a relatively low hysteresis or a loss angle on the order of from about 7.degree. to 13.degree..
