This allows the tire to improve the steering responsiveness and the driving stability. The better road contact and grip upgrades the tire's response time and accuracy to the driver's steering instructions, while it secures the structure against the driving pressure and stabilizes it. The strengthened structure also helps enhance the stability, along with the durability. The full steel belt and polyester cord reinforcement maintains the tire's ideal shape under the load and driving pressure. This significantly improves the load carrying and withstanding capability, which greatly increases the load capacity.
