I have a better solution for you than the tire you referenced. The part # TTWTRTM2057515C is the exact same size as what you have and is also a radial tire.

The # TTWTRTM2257515D would be a bit larger than what you currently have and has the less preferred bia-ply construction.

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.
