The advantage of a radial tire is undoubtedly the enhanced performance. Rather than running the cords diagonally, radial tires feature cords that run straight across (90 degrees from the tire’s centerline) from bead to bead. This helps stabilize the sidewall and tread patch, while using less ply material. Additional strength comes from layers of steel belting that reside beneath the tire's tread. These design characteristics provide more flexibility, and allows the tire to better conform to the road's surface.
