The main difference between a radial ply and a bias ply tire is how the tire is constructed. The cords inside a bias ply tire run at a 32 degree angle to the direction of travel, and the cords on a radial tire run at a 90 degree angle to the direction of travel, or across the tire from wheel lip to wheel lip.
A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear.
A radial tire will normally run cooler than a bias ply tire, especially when the tire is under a load. A tire that runs cooler will last longer.
A bias ply tire has a stiffer sidewall than a radial, a feature that is useful for off road applications like farm use.
For a wheel and tire with the size you need I would recommend the # MX97FR which comes on a wheel with a 5 on 4-1/2 inch bolt pattern like what the axle you referenced has. This is Load Range D and has a higher speed rating of 81 mph.
