What are the differences between a radial and a bias belted tire?
The body plies are perpendicular to the bead on radial tires. On bias and bias belted tires, they are at an angle (bias) to the bead, which greatly increases sidewall strength and durability. The belt on a bias belted or radial tires improves tread stability and helps reduce rolling resistance which is the radial tires main feature. M/T’s construction sandwiches the belts between the body plies, which improves ride and virtually eliminates belt and ply separations. Sandwiched belt construction is unique to M/T tires only.
