What is the difference between bias tires and radial tires?

[MariaFitz]

The difference between bias tires and radial tires lies in the arrangement of the cord plies in the tire carcass. Radial tires have a thicker tread crown, offering excellent wear resistance and the advantage of low rolling resistance, while bias tires generally have a longer service life. Below are details about bias tires and radial tires: 1. Bias tires are a traditional type of tire structure, where the cord plies and buffer layers are arranged in a crisscross pattern at an angle of less than 90 degrees to the centerline of the tread. 2. Radial tires differ from bias tires in their cord ply arrangement; the cords are not crisscrossed but are instead aligned nearly parallel to the tire's cross-section, resembling the meridians of the Earth, with a cord angle typically at 0 degrees.
