What is the difference between radial tires and bias tires?

[GageLee]

The differences between radial tires and bias tires are: 1. Different materials: radial tires are steel wire tires; bias tires are nylon tires. 2. Different cords: the cords of radial tires are arranged nearly parallel to the tire cross-section; the cords of bias tires' carcass and buffer layers are crisscrossed. 3. Different carcass structures: the cords of radial tires are wound side by side, and the top layer of the carcass usually contains a steel belt made of steel wires; the carcass of bias tires consists of crisscrossed cord layers. Both have limitations in use. Generally, bias tires have greater sidewall stiffness, resulting in poor ride comfort, especially at high speeds when the tire temperature is high and heat dissipation is difficult. Additionally, most bias tires use nylon cords as the stress layer, which can lose tensile strength under alternating cold and hot conditions, increasing the risk of tire blowouts. The disadvantage of radial tires is that their sidewalls are thinner and prone to cracking, leading to poor lateral stability of the vehicle, and their production costs are also higher.
