		HIGH ELONGATION STEEL CORD We Use High Elongation Steel Cord In Our Fourth Belt, So You Don't Have To Give Durability A Second Thought. Some tire makers offer a fourth belt, or protector ply, of high elongation steel cord only for their on/off highway tires. Toyo uses its High Elongation Steel Cord in all of its premium radials, both over-the-highway and on/off highway, for maximum durability, whatever the conditions. Our High Elongation Steel Cord features filaments with tight twists, wound like a spring, to better protect the tread area. Toyo's four-belt design, combining a High Elongation Steel Top Belt and Belt Defender, protects against cutting, chipping, and impact breaks for outstanding retreadability.
