An improved pneumatic radial drive tire (10) for agricultural use under dry and wet or moist soil conditions requiring a tire with high flotation and deep tread characteristics is described. The improvement comprises utilizing a tread (13) with a net-to-gross ratio in the range of 15 to 25% and where the tread (13) has lugs (18A,18B) that are greater than 150% of standard R1 lug and greater than 75% but less than 95% of an R2 lug. The lugs (18A,18B) when incorporated in a 20.8 R38 radial tire are designed to support and carry for extended distances a dynamic load bearing weight of 170% of the Tire and Rim Association's recommended load on paved surfaces without lug failure. <IMAGE> |
