What is the difference between radial and bias tires?

[FinleyRose]

Differences between radial and bias tires: 1. Different cord arrangement directions: The cords of radial tires are arranged at a 90-degree angle to the centerline of the tread; the cords of bias tires are arranged in a crisscross pattern. 2. Different stress-bearing parts: Radial tires have a sturdy steel belt layer as the main stress-bearing part in their structure; the main stress-bearing component of bias tires is not on the cushion layer, with 80% to 90% of the internal stress borne by the cord body of the tire. 3. Different performance: Radial tires need to withstand greater tangential forces during driving. To ensure the stability of the cords, there are several layers of high-strength, non-stretchable material belts outside them; the sidewalls and tread of bias tires are stronger and more rigid, resulting in poorer comfort.
