Bias Tire
Bias tires are used primarily for off-the-road, agricultural, and industrial vehicles. Bias tire construction utilizes body ply cords that extend diagonally from bead to bead, usually at angles in the range of 30 to 40 degrees, with successive plies laid at opposing angles forming a crisscross pattern to which the tread is applied. The design allows the entire tire body to flex easily, providing the main advantage of this construction, a smooth ride on rough surfaces with stronger sidewall resisting scratch and abrasion.
Radial Tire
Radial tires are produced for passenger cars, light trucks, trucks, and buses. Radial tire construction utilizes body ply cords extending from the beads and across the tread so that the cords are laid at approximately right angles to the centerline of the tread, and parallel to each other, as well as stabilizer belts directly beneath the tread. The design offers the tire with longer tread life, better steering control, and lower rolling resistance.
