What is a Bias Ply Tire?

[VonElle]

Bias ply tires can be simply referred to as nylon tires. The following is an introduction to bias ply tires: 1. Structure: The carcass plies of a bias ply tire are composed of multiple layers of rubber-coated fabric. The adjacent plies have the same cord angles and are arranged in a crisscross pattern. The number of plies is usually even, which helps distribute the load evenly across the carcass plies. 2. Specifications: Bias ply tires are typically marked with two sets of numbers connected by a hyphen. The first set indicates the section width, and the second set represents the rim diameter. 3. Related Components: The tire casing consists of the tread, plies, breaker, and bead. The plies form the skeleton of the tire casing, maintaining its shape and size. They are usually made by bonding an even number of multiple layers of rubber-coated fabric (plies) with rubber. The angle between the ply cords and the tire's radial section (crown angle) is generally between 48 and 55 degrees.
