The pneumatic tire for use on drive wheels of general-purpose agricultural tractors performing field and transportation work has a tread comprising uniformly alternating and subdivided grousers arranged in a "herringbone" pattern at a variable angle to the equatorial plane of the tire. The tread cap includes a central zone (A) featuring the highest tread pattern saturation and intermediate (B) and shoulder (C) zones adjoining said central zone on both sides. Assuming the tread cap zones (A, B, C) to be equal in width, the ratios of coefficients (Kb, Kc) of tread pattern saturation in the intermediate (B) and shoulder (C) zones to coefficient (KA) of saturation in the central zone (A) are in the ranges of from 0.85 to 1.0 and from 0.75 to 0.85, respectively. <IMAGE> |
