Bias ply tires are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.
Refer to your existing tire sidewall and/or trailer owner's manual to determine the appropriate tire size and load capacity for your application.
