With the construction of the tire a polyester cord is placed exactly under the center rib. Then C3M Technology and the precise placement of high performance Aramid fiber cords are above and below the belt package and along the shoulder of the tire. Next a precisely placed high modulus “under-tread” in the shoulder area. Now the outer layering has a special all-weather compound designed to maintain flexibility even during below-freezing conditions, an optimized center rib wet-weather compounds and variable-width sipes, the unique placement of road-gripping rubber compounds are, and Tri side-by-side compounding, which places three different rubber compounds across the tread.
